My system: i5 760 (quad), HD 6870.

The game had a little lagspike
and I wanted to know why, so I started by opening HWMonitor to check
the processor temperature. They usually never go far into the 60s on
games like The Witcher 2. Later I opened the task manager and what I saw
was strange indeed. The first code went up to 100% often, the other
three were in the 90s. I restarted the game and was out of combat, but
the CPU usage was the same, though core 2 through 4 had 5-10% less. I've
seen the same happen in DA2. The Witcher 2 barely uses my processor
when I alt-tab, but DA just carries on stressing it.

Once I shut down the game, all calms and the temperatures skydives down to 40C.

Is the game really that heavy on the processor?

EDIT:
For the purpose of this not being a problem with my computer, I tried
with the Witcher 2 and compared to Dragon Age doesn't even get to 50%
when I basically just standing about.

EDIT2: If it might prove
useful to know the location where I noticed it. It's during the Nature
Of The Beast quest when you are in the large room in the lower ruins
with the Arcane Horror that will teleport if you try to attack it with
meele.

EDIT3: DA2 didn't have this problem at all, thought it happened once, but I can't reproduce it. It was during Legacy though.

EDIT4: Yes,
I have googled, but not found anything that's not a year and two
patches ago. The excessive use creates heat and might explain while my
laptop went infernally warm when playing.

My laptop, few months old now but an i3 processor, heats up massively when I play DA:O as well. It doesn't occur for any other games I have, though I can't test it for DA2 as ive only got the PS3 version of that. So it's not just you, although I don't know if it is a highly common issue or not.

[0x30A88]

I fixed the temperature increase at leasat by making sure the processor leaves core 1 and 4 alone. It does give the two remaining cores hell though.

I suspect there's a loop without any pause going on in the code. Full force seems excessive out of combat though, and even within combat.

DAO has issues with more than 2 cores. It's a known issue listed in the solutions round-up thread pinned to the top of the forum along with directions for setting core affinity. The game engine leans on the CPU more than most games do (one of the many reasons that laptops are not supported). The devs seem to have streamlined the CPU usage for DA2 as well as adding in routines to handle multi-core processors better.

The problem was only that it increased the temperature, as is the greatest danger to CPUs.

Edit: Ignore me.  More coffee is clearly needed.

One of the many reasons that gaming on a laptop is generally a bad idea is that the systems simply don't have adequate cooling capacity.  There isn't enough room.  The fact that it is nigh on impossible to get a decent graphics card in one without buying a system that weighs as much as a small car and is roughly as expensive is another.  My two year old core 2 duo on my desktop doesn't warm up more than 5 degrees C even after playing DAO for hours.

My computer's case also offers little possiblitiy for efficient wiring.

If you plan on using it for a lot of gaming, you might want to consider upgrading the case and CPU heatsink.  That is far cheaper and easier than replacing fried components.

[0x30A88]

My computer's case also offers little possiblitiy for efficient wiring. The case is well wentilated though with three fans and one large one.

[sami jo]

Lots of fans and generally good ventilation doesn't always mean good airflow over critical components. Your chip really shouldn't be heating up that fast.

It's just a thought. I'd hate for your CPU to get damaged.

[ejoslin]

I want to second what sami jo is saying about cooling. If your CPU is heating up quickly, getting a better fan may help. Also, using a thermal compound like arctic silver I really believe makes a difference.

Edit: Laptops are harder to keep cool.  I also think DAO's engine is not very efficient, but gaming on laptops normally does lead to a hot laptop.  I don't think you're going to see changes in DAO.  If you don't want to actually open up your system and such which can be a pain, at bare minimum you can get a cooling pad cheaply with fans built in.

Are there better coolers that won't need me to change the bracket behind my motherboard, the one the screws sit in? Processor: i5 760. Running DA:O on only core 2 and 3 keeps the temperature stable, without sacrifising performance.

No other games have heated it up, except Battlefield 3, though that one is still in alpha. DA2 did it once during Legacy though.

I believe you're using a desktop -- you should be able to find a fan that fits your needs. One thing I will recommend again is using a better thermal compound such as Arctic Silver (I'm not a shill for them, but I've been using that particular brand for over a decade when I build PCs).

[sami jo]

You shouldn't have to do anything to your motherboard. Most CPU fans connect to the CPU itself. Ej is right about a good thermal compound (and thermal compound is fairly cheap). It will improve your cooling fan's ability to pull heat away from the CPU. Sites like Tom's Hardware have reviews of these things to help you find one that is good and fairly inexpensive.

[Gorath Alpha]

The Arctic Silver mentioned gets a lot of play from reviewers, but since it actually requires days or even weeks before it actually is at its peak, is at best just a supremely expensive waste, or just someone trying to show off that he/she knows the "right stuff" to refer to.

Proper usage of the material can't be overemphasized ~~ you want the very least possible, the thinnest layer you can apply.

Regarding the bracket, you'll have to read the description of the aftermarket replacement heat sink assemblies and eliminate those that demand any new backside bracket (although the very latest of gaming case designs now feature cutouts in the MB tray for access to the back bracket without having to dismount the MB).

You know, I've been building computers for a couple of decades (I'm 42), and I overclock my boxes -- it's a brand that works, and I'm not sure how you consider a product that costs about $10 USD for enough of the product to last a lifetime supremely expensive.  What you're saying really doesn't make sense as far as a curing or whatever.  All it is is a thermal compound.  Most fans come with thermal tape, and thermal compound works much better.  You put on a VERY thin layer (very very thin) and affix the fan.

By all means, always take advice you get on the internet with a grain of salt, but you really don't have to be insulting  I wasn't trying to show off -- I was trying to help someone.

Have a great day!

I've noticed better thermal efficiency when I use thermal paste/grease. It's anecdotal I know, but the drop of temperature is noticeable and it happens every time I use the stuff. As for brands, the real danger is that the no name stuff may not be as represented. Going for the name brand provides some reassurance in that regard.

If the OP really wants to get the maximum cooling, then he/she might consider a water cooled set up. Or even oil or liquid nitrogen.

[Gorath Alpha]

My point was that if the reviewers all did use Arctic Silver for every review, on systems that get broken back down in mere days, then the product has never had time to apply its superior qualities. I would imagine, moreover, that I've been building PCs as long or longer than anyone who belongs to the forums, having begun in 1986 or 87, when the 80386s were fairly new, and very expensive if you didn't built the PC yourself.

I've only built a hundred or so of them, of which maybe 16-17 were for my own personal use.

I've been building for a long time as well.  I stand by my advice of using using thermal compound over thermal tape and Arctic Silver over a brand x as the company itself does have a reputation they want to uphold.  It's not an expensive thing unless you're going through a bulider who charges a ridiculous amount for it.  I personally use it but I don't charge extra for it since it is so cheap.  

As far as reviews go, I have to admit I don't read reviews of thermal compounds -- I just was recommending something that I've used for years and years.  

But the point that you should always do your own research and not just blindly follow forum poster X is a good one.  I agree with that 100%.

Edit: I did a major edit to this because my point really did get lost along the way  Some things are relevant, most are not!

I use thermal tape and since this is my first -- and only -- build, I would be hesitant to grease up my CPU. I would perhaps do it if I am to change the cooler.

Can you recommend a specific cooler? I just noticed my case have the possibility of opening behind the motherboard, so installing a new bracket wouldn't be that hard. I wouldn't go through all the hassle with a water cooling system.

Details:
Motherboard: ASUS P7P55D
CPU: Intel i5 760

FYI, thermal compound is really easy to use and you aren't going to break your system using it. Back when my son still thought it was cool to help me, he used to be the designated thermal compound-applyer. This started when he was about six or seven.

As for suggested heat sinks, I always check out a couple of review sites like Tom's Hardware and read the customer reviews on New Egg. Unless you are overclocking, the water or oil cooled ones are probably more than you need. Someone else may have a favorite brand. I tend to just go with whatever is cheapest of the ones with good ratings that will fit in my system.

would that one fit.

1156 means LGA1156 right?

Sadly, I have absolutely no clue what it says.  I would imagine that it is referring to LGA1156, but since I can't read any of it, I'm not sure. 

After a brief search of reviews, here are a few suggestions:
http://www.rwlabs.co...00&pagenumber=7 (~$70 online)
http://www.newegg.co...3-065-_-Product (~$30 online)

I've used both brands in the past.  The aligning pin can be a bit tricky on the CoolerMaster (the second one) but once aligned properly, it works well. 

[0x30A88]

The CoolerMaster seems good enough according to reviews, and I found it on the norwegian shop.
