I'm planning to reuse Case Fans from a prior build, but i'm considering reinforcing my Case Fan supply in my new build because i've heard that my Graphics Card choice (Already arrived! ) is sometimes getting dangerously hot in some builds. I find myself wondering if such people are upgrading to the card from a weak one that stays cool easily & they may be failing to realize how hard this one will be working at it's job & failing to ventilate their case adequately & might be getting too much hot air buildup in their Case. (Theory, for now.)

I want my CPU & Graphics Card to both have long lives, so I think my old Case Fan setup was adequate for my old needs, but might need to be powered up in this next setup. (This old setup uses a stupid Onboard Graphics Chip that didn't even need a Heatsink. That won't be the case this time.) The old setup only had 2 Case Fans, one set to pump air into the Case, one set to pump air out of the Case. My Case can hold 5 80mm Case Fans. 2 Case Fan ports side by side on the back, 2 Case Fan ports on the lower front, & 1 Case Fan port on the left Side Wall with a transparent window. I've attempted to find a Dual Fan unit to handle 4 of those ports with only 2 connectors, but i've only ever found 1 Dual Fan item after gobs of searching, & I can't determine for absolute certain if it'll fit in my Case, or if it's a little too big/bulky: (Or if it's even designed for use in a Home PC Case at all.)

8cm Pc Expansion Card Coolingfan

This one might be a bit loud for practical PC use as well, but still, why is this type of fan so hard to find? Anyone know of a 80mm Dual Fan or similar? It'll be quite a task trying to hook up 5 individual Case Fans... 3 Connections is a LOT easier to manage. I have 2 SYS_FAN Ports & the 3rd can easily go 4-Pin Molex. I'd rather not need 3 4-Pin Molex hookups, but i'll try if I must.

I also will need at least 1 normal 80mm Case Fan. 1st, I seek intel on some of the attributes of Case Fans:

Bearing Type: Is there any relevance to differences in Bearing types? Are they even worth worrying about?

RPMs: How relevant is this? Is there a particularly strategic RPM zone to aim for, or do I wanna go as high as possible? (Though it seems like higher RPMs have higher noise, & this seems to be relevant to watch out for.)

Air Flow: I take it this is a measure of how strongly the Case Fan moves air, which is of course the primary job. Is it possible to overdo it on this stat, or do I wanna aim for the sky? Is there an Air Flow threshold level that could be considered weak & inadequate?

Noise Level: Approximately what dBA is rougly comparable to a 'soft' low hum'? That's what noise level my current Case Fan's noise level is at normal operation, & it's been acceptable to me. I don't ever feel distracted by it. I need to know this so I can know what dBA to set as my max acceptable criteria for this stat.

If I can understand these stats better, I could get an idea of what search criteria I would wanna aim for in my Case Fan research.

Another consideration is that i've noticed that some Case Fans (including one current use one as of the time of this post) have a 4-Pin Molex that has both a Male & a Female end. This appears to be designed to enable daisy-chains, but how long a chain can ya make & still get full power on everything in the chain. Is there a way to tell or plan this out? Does it depend on the power of your PSU?

Lastly, i've noticed that the Case Fans seem to have the (hope i'm referring to this right) 'front cap' part of the fan of the Case Fan opposite of the Wires as the Front of the Case Fan, & this seems to always be the direction the air is being blown toward. Am I right, or are there exceptions to this that make me have to beware? & is there official terminology for various parts of Case Fans aside from the Fan itself?

My apologies if this post is too big. The intel on the Case Fan Attributes is most important to me, the other stuff can be ignored if it's too annoying to read.

[Tyrax Lightning]

My puder has a ways to go, but it's coming along:

Now I need the RAM & PSU. Then Windows 7. Then I will get to find out if all goes well with my build.

I'm still concerned about my Case cooling power:

I've gone through a LOT of trouble building this new puder, & i'm unsure if my current cooling needs are adequate. The rear Case Fan in the back, & a Case Fan on the Side Wall, (not shown) might not cut it. There looks like a potential Hot Air build-up area that could threaten my Graphics Card, & I want it to have a long life. The Side Case Fan not shown is about dead center of the Case, approximately above the lower part of the RAM Slots. This doesn't look adequate.

Even if I get 2 Case Fans on the back in Outtake mode, 2 Case Fans on the front in Intake mode, & the Side Case Fan in Outtake mode, i'm still concerned that it might not cover this Hot Air Pocket danger. Does this look like a situation to consider a PCI Slot Case Fan?

I seriously hope i'm not getting annoying, but I don't wanna get this new puder built, only to blow it up. Many thanks for your time.

Is it hard to build your own system?thinking of building my own soon.

[Tyrax Lightning]

Yes. It's complicated & difficult, especially handling the Motherboard, the most fragile of all the puder parts. But success can be VERY rewarding. Bein able to assemble your puder yourself is also a cash saver. The biggest dangers are accidential part incompatibility, part damage, (especially the aforementioned Motherboard) & static electricity. (Guarded against with an Electro-Static Wrist Strap or similar device.)



The 1st couple builds are seriously hard. Once ya know what your doing, it's much easier, but is never something ya can just sleep through. It has it's ups though, including being able to kick weak stuff outta the build & make sure ya get strong puder parts. The Heatsink in the above Pics is such an example. The Stock Coolers & Thermal Grease that CPUs naturally come with tend to stink. For my build, I got the above Heatsink that's much stronger than a standard one, & powerful Thermal Grease. Bein able to make sure you're not stuck with weak stuff is the biggest plus to self building Puders.

[Sa Seba]

If you put two in the front and two in the back, you will be fine for now. You might want to consider another case at some point. For good cooling and function you pay about 60-70 dollars (Antec 300 plus 2 fans, for example).



Seanzie88, if you need help choosing parts, just ask here. Building it with your own hands is maybe a bit tricky the first time but if you are somewhat handy, you will enjoy it.

Most stores also offer a custom build option, if you want them to put together the parts you chose.

[Tyrax Lightning]

I've noticed a Vent on the Graphics Card & wonder if it has to do with the Hot Air Pocket danger, but I can't tell if it alone is enough to vent out all of the hot air. It looks like the vent might be designed to work together with the Intake Fans, but does it look like enough to get the job done? It's kinda small...

Hope i'm not bein paranoid, but a puder loss on this new build could set me back more than I could recover from...

In my research, i've found a potentially awesome item:

Nexus PCI-300 Extra Ventilation PCI Brackets

They look like they're for the same purpose as the Grill Slot naturally built into my Graphics Card, providing a place for Intake Case Fans to push hot GPU air out of the Case. If I put 3 - 4 of these into the slots below the Graphics Card i'm not gonna be stickin a card in, & combine this with very high airflow Intake Mode Case Fans on my Case front, (to hopefully provide enough air for both the top & bottom of the Case) could this completely solve my Hot Air Pocket danger?

What anti static measures should ba taken when building,rubber gloves?

[Tyrax Lightning]

This kind.  Though mine's yellow. Color doesn't really matter for these as far as I know.

The current Case is conking out along with the rest of the puder. My Case I was gonna reuse for the build was run harder than this one before it went off duty, so I mighta been wrong about it having years of life left after all.  It looks like i'm stuck havin to get a new Case after all.

I've researched Cases & found 2 contenders. I can't afford to go higher than these 2 in price range:

Sunbeam Quarterback IC-QB-SVBK Silver/ Black Steel ATX Mid Tower Computer Case

I'm concerned about this one because it's Center Fan Mount might not accomodate my SAPPHIRE 100258-1GHDMI Radeon HD 4850 Graphics Card, but then again, it's Case Fan setup power looks powerful! This one holds 4 120mm Case Fans, 2 middle, 1 side, 1 rear.

VS

Broadway Com Corp FX-Series FX-SILVER Black / Silver SECC Steel Computer Case

This one holds a 140mm Case Fan on the front, 1 120mm Case Fan on side, & 1 120mm Case Fan on rear. This one looks the better bet. Will 3 Case Fans be enough?

I've measured the dimensions & both will work, including the Case dimensions being clear for my CPU Heatsink. Also, my new build Motherboard is ATX, so the Motherboard Form compatibility is green.

Which looks the better bet?

Edit: I've examined the Broadway Case Pics on NewEgg with a lot more study now, & it looks like the NewEgg Specs are screwing up again. It looks to me like it can hold 4 Case Fans, not 3. The specs say 1 120mm side fan, but the Pics show 2 side mounting locations.

I also further studied the Sunbeam Case, & a couple of the reviews report a !!! Magnet !!! powered front door! What madness is this? Magnets & puders are enemies!

I'm really leaning toward the Broadway Case now. My apologies, this Case choice feedback question mighta been a waste of time.

OK, for one, you never listed your specs. Two, you have your CPU cooler back to front, the way you have it in your pics it will be blowing hot air onto your RAM, not good. What you want in a case is space and fan slots. Don't waste time looking at brands, you won't find a good brand name case on a tight budget. Look at cheap large cases, you should be able to pick up a decent sized midi tower for about $20 - $50. I would suggest one with a side pannel fan and perhaps even a blow hole (fan on the top of the case). As for the fans, most systems will run fine with 2 120mm fans, one in and one out. Even more important than the amount of fans though is management, cables, expansion cards and peripherals should all be aranged so as to allow maximum airflow with the devices that get hottest near an outlet fan so they don't build up heat in the system. It just takes a little thought. Building a system is easy and streight forward, any idiot that can read a manual can do it but it takes practice and experience to do well. I have built litteraly thousands of systems from HTPCs to blade servers and the thing I have found to make the most difference in a build is planning. Before you start, sit down, look at all the parts and then figure out where to run cables, place the drives and fans to allow maximum heat expulsion. That is what you want, all the fans in the world do little good if they are just pushing heated air around the case.

Go simple with the case, I have a $1000 system in a $20 case and everything runs cool and efficient. I can't even hear my fans over the sound of the breeze outside my window. Plan, build, enjoy.

Oh, and Nexus make some good cooling gear, I have reviewed a lot of their products and only had one (of 10) fans fail and that was under extreme duress. Good luck with your build.

Motherboard: GIGABYTE GA-MA770T-UD3P AM3 AMD 770 ATX AMD Motherboard. In build.

CPU: AMD Phenom II X4 925 Deneb 2.8GHz 4 x 512KB L2 Cache 6MB L3 Cache Socket AM3 95W Quad-Core Processor. In build.

Heatsink: Cooler Master Intel Core i5 compatible Hyper TX3 Socket 775/1156/AMD 130W 92mm "heatpipe direct contact" CPU Cooler RR-910-HTX3-G1. In Build.

Thermal Grease: ARCTIC COOLING MX-2 Thermal Compound. In build. (Undecided on whether or not i'm stickin this on my GPU as well. Might watch my GPU temps & find out if it's warranted or not first.)

Graphics Card: SAPPHIRE 100258-1GHDMI Radeon HD 4850 1GB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card. In build.

PSU: OCZ Fatal1ty OCZ550FTY 550W ATX12V / EPS12V SLI Ready CrossFire Ready Modular Active PFC Power Supply. Not yet acquired. (This PSU has !!! 25 Amps !!! on it's 12V Rails! )

Case: Broadway Com Corp FX-Series FX-SILVER Black / Silver SECC Steel Computer Case. Incoming. (As of the time of this post.)

RAM: Not yet determined.

Windows 7 64-bit: Not yet obtained.

This Case is $50ish bucks & $18.48 Shipping, but it's coming with 3 Case Fans with it. After it arrives, i'm gonna examine & attempt to research the Case Fans & try to find Specs for them, & try to determine if they're ok, or if they suck. (If they're ok or better, then they've helped make this Case a sweet deal. If not... then the Case still looks like it'll suit my needs.)

I set the CPU Fan to point Left toward the back. It's planned to pull the heat off the Heatsink & through it, & shove that hot-air straight into the rear Case Fan. (& the rear Case Fan is, of course, gonna be set in Outtake Mode.) I double-checked it's orientation & it is indeed pointing in the right direction. The reason I planned it like this is that it's the Fan that's gonna go into the Motherboard CPU_FAN plug, so I figured if it's pulling the Heatsink air into it, it'll have an accurate intel on the CPU's approximate temperature. (The Case Fan that came with the Heatsink is 92mm & equipped with PWM.) If I set it to be a 'push the air through the Heatsink' setup instead, how will it be able to tell with any accuracy the CPU Temps?

Another thing about this Case choice that's the biggest reason why I chose it: Take a look at the above old Case setup that got cancelled. I was concerned about a Hot Air Pocket Danger Zone. This Broadway Case has 2 side Case Fan ports. One of them is on the lower rear of the side, right on top of this Hot Air Danger Zone. I'm planning a Case Fan in Outtake Mode to completely safeguard this entire area (especially the Graphics Card) from this danger.

The other side Case Fan port is above this, on the upper rear of the side. This one I haven't finished planning yet. After I get the Case & get the parts transplanted into it, I still need to plot if I would wanna Case Fan here in Intake, or Outtake Mode, or if i'll even need a Case Fan here at all. On the one hand, I wonder if an Intake Mode Case Fan here could blow cool air right onto the Heatsink & backup the CPU Heatsink Fan & outright baby my CPU. On the other hand, I dunno if this would disturb the CPU Fan airflow instead. If I put this same side Case Fan in Outtake Mode, once again, i'm not yet sure if it'll reinforce the CPU cooling, or disturb it.

Hope this is enough info. Sorry bout forgetting to think about the Specs info, i've been researching my head off & it's makin me addle-headed at times.

Edit: Almost forgot, I gotta IDE DVD-ROM bein reused just to get all the bucks it cost used up, then it's gonna be replaced by a SATA DVD-ROM (3.0Gb/s) & IDE will be extinct!  Alternatively, if this current IDE DVD-ROM goes down before my puder is done, i'll happily stick mine in this puder for my Mom to finish up the lifespan of & get the SATA one sooner!  She doesn't hard-core game, so she doesn't need as much power in her puder setup.

Edit 2: I remembered to check Motherboard Form Compatibility with Case Compatibility, & am clear. I'm also certain that everything i've got parts-wise has adequate clearance. This Broadway Case is even giving me a little more Width than what my old one would have.

Edit 3: My Heatsink has the option to hold a 2nd Fan to create a Push - Pull system. I don't know if i'll need it, but if I ever do, I have the option.

[Xaltar81]

Push or pull setup on the CPU cooler shouldn't make a difference in reading the CPU temps. Most coolers are set up with the fan pushing air through the cooler by default, I assumed that was the case with yours. So long as the air is being pushed toward the exhaust fan at the back it should be fine. Once your system is up and running you can try it in both push and pull setup and see which config runs coolest. With a 95w CPU though your temps should be pretty good. Make sure your fans are as balanced as possible (air being drawn in ~ air exhausted). Keep up the planing and research and enjoy your build. Just be sure to test that everything works before you put hours into routing cables and tightening screws etc

[Tyrax Lightning]

Many thanks for the info! I admit i'm new to PWM.



Too late on the hours of cable routing & screw tightening. I'll have to put up with that transplanting the stuff from the old Case to the new Case. It's gonna be scary having to handle the motherboard again, but I gotta do what I gotta do to get my new puder.

[Dark Lilith]

mine has fans and is also water cooled,which I find is more reliable than fans since fans rely on the room air temp where water-cooled is a chilled sealed system like on a car.

I've heard of water cooling systems, but don't know anything about them. Interested on intel on them. Isn't it scary to think of them springing a leak?

 When my x1650's cheap fan died. I put in one of these: www.titan-cd.com/2009_WEB/product/fansystem_en.asp
TTC-003, to be exact, and I never had any problems with it after that. It was cheaper than a new GPU fan and I can use it in my new computer as well. Just pop it under the GPU and the fan will suck air from above it.

[Tyrax Lightning]

Many thanks for the intel. I'll keep it in mind if I catch my Graphics Card experiencing heat problems.

[Tyrax Lightning]

Woohoo!!! I've managed to test the 3 Case Fans that naturally came with the Broadway Case, & all 3 are moving good air while being pleasantly quiet! They're build worthy! (For those of ya that might need a new Case & require quietness in your Case Fans, ya wanna consider getting the above Broadway Case! It isn't everyday that puder stuff comes with additional parts that don't stink.)
2 of them are Blue LEDs. The LED effect looks sweet!  (Performance 1st. But Performance + LED can only be better. )
