open top case is...well, i googled open top case pc cabinet, and lol - first thing that came up was the exact same cabinet that I use.
Here is a pic of it. You cant see it from top, but if you look at the grills on the side there, it has that type of grill on the whole top of the cabinet. And then I mean, the WHOLE top -.-
My boyfriend has a similar cabinet, not the same, but also open top. He`s came with a removable screen - mine didnt ofc... After he saw my pc, his eyes turned big, he turned around and started to dismantle his own pc. He`s was even worse, cause he has his pc on the floor, and omg - he uses it like a footrest when he is watching youtube (We are kinda Yogscast-fans, gotta love Sips
)
Anywho, he`s was even worse, so he had to do like me: Take the whole fan off to get it clean. It was bad, we had to improvise, so some of our tools was q-tips, vacuumcleaners, paper and a tine dash of water to get the dust out of every crack, lol ^^
He put his screen on again, and I improvised by using a piece of cardboard. To make up for it I removed the middle plastic plate in the middle of the front, altho it has already airflow from under it and both sides. It hasnt gotten any warmer inside, so its fine.
I`m gonna improvise and make my own little grill for the open whole at the front when I get around to it. No matter what, its the top thats worse. Everything in the air not even fall down but is getting sucked in from the fan. bad design id say.
And to make it worse I got this dogbreeds: Rottweiler, labrador and a little fluffy hairball called mittlespitz. Those breeds make the most FANTASTIC dustbunnies: the fluffy mittlespitz-hair make the dustbunny nice and big and soft and airborn - then you add stiff rottweiler/labrador-hair into that and you got the most amazing hardcore ball of hell that gatheres up everywhere in every corner 
On top of that I also got a black shorthaired cat that adds it into the mix. 
Wow, im so good at getting sidetracked! I humbly appologise! 
Back on topic:Melissa:
Yes, I did that yesterday as one of my projects. It indeed came another update for my nvidia yesterday. Before I installed it i rolled back, but no luck.
Yesterday I also tested some more sweetfx. Tried the 2.0-verson wich worked magically, but its only 2 presets out for that one so far, and I did not like any of them. Gotta wait until someone put out one 2.0 i like ^^
So now I have installed k`putts config. As it is with every 1.5-versons I try it makes my loadingscreen go all weird like I explained earlier, unfortunately its also become very visible ingame, but its playable. Everything is playable if you just wanna play hard enough 
In between I am testing new things still, I am utterly baffled over all this.
Checked my fps yesterday too, its jumping between 45-60 fps. Tested different graphic settings, didnt do much.
I have used "user.cfg" file to get in: WorldRender.MotionBlurEnable 0
I`ve also done this: ""Forcing VSync and Triple Buffering off using the above commands in your "user.cfg" file and forcing them back on via your GPU driver control panel can eliminate stuttering and screen tearing during cutscenes, without affecting input lag.""
increased fps a bit and helped on the tine bit of tearing that was left. Thats now gone.
This is tips from THIS page.
I downloaded the HWiNFO64 but my skills didnt live up to finding where the temp was....ahem. I took a screenie, maybe you can guide me
