New i7 2600k working my GTX 295 too hard?

post #1 of 24
Thread Starter 
Hi All,

i put myself together a nice little setup, overclocked it and it runs great!

however, on my old q9550 platform, my gpus were never pushed as much as they have been now. for example, in crysis you would see them sitting at around 80% load. Now with the i7 they are maxing constantly at 100% - giving me astonishing performance but with a cost of much higher temperatures!

my 295 was hitting 93C with the fan on 100%! any fellow i7 owners with an old 295 that are finding the same? any suggestions short of building a wind tunnel in my study?

I've already got good airflow.

cheers all

might be time to upgrade GPU's, surely a 550 or 560 would be manageable

Umm..... a 295 would blow a 550 out of the water....

What you need to do is either a) Clean the heatsink out, there is probably tons of nasty stuff in there making your temps higher, or b) reapply the thermal paste on the gpu's.

Hmm... Maybe your 295 was being bottlenecked before? That would explain why it is suddenly getting more usage. It doesn't really make sense that your previous CPU was bottlenecking it though.

Welcome to UNBOTTLENECKING effect .
As said before ur gpus were working sync with ur cpu. Now u have a really fast cpu so they are working great. Its a good thing to have high % load on the gpus.
If u turn vsync on the temps will drop as the gpus are only working to give stable fps.

Well indeed, the unbottlenecking effect is quite something, i knew i would get a performance gain but this is quite shocking!

Thank you for the input all, i wanted to open it up and give it a clean but its the dual PCB edition, might be more trouble than its worth.

as for vsync, that's turned on (Quick edit, i did notice that vsync wasn't working correctly in crysis, the fps would jump suddenly to 70/80fps and back down again)

one thing to add, the card makes a slight squealing noise now. i was wondering if its on it's way to the big graphics card bin in the sky.

I'm currently idling at 65c fan on auto in a very hot and stuffy room.

Your very hot and stuffy room doesn't help - make sure that you have low ambient temperatures - also the dual PCB cards tend to run very hot. Cleaning out the heat sink shouldn't be more trouble than its worth, it should go along with proper maintenance of a computer system - its a beastly card just work with it, you'll be happier in the long run

The PC is Dust free, and is kept that way through regular maintenance and the use of filters. But i'll give it a bash!

just found some interesting stuff on google. apparently a lot of these cards squeal like piggies under the fullest of loads so that would most likely explain that. either way or a cap is about to blow. lol >.<

Most study s in the UK are not equipped with the luxuries of AC Appleg33k85 so adjusting my ambient room temperature is as scientific as opening a window unfortunately .

Thank you for your input all.
