Well I agree to a degree, however, my room ranges between 17 degrees, and 27 degrees at it's hottest. On my GTX 470 with the VF3000F cooler, depending on the temperatures in my room has the same 10 degree difference "idle" occasionally goes even higher, a few weeks back my temperatures were 33 degrees idle, now they're at 44 degrees idle, which is a fair difference but never gets hotter than 70 degrees.
Now, I have positive flow in my case, as it utilises the [ame="http://www.youtube.com/watch?v=douRh490E3I"]stacking
effect[/ame] when my room is at 27 degrees, I'm pumping the hotter air in, thus my temperatures increase.
If I were to be effectively sucking that air out, reversing the fans to exhaust instead, (which I haven't tested), I'm assuming either one of two things will happen:
- Fans won't be as powerful, and will not be able to cope with sucking air out of the case as well as they do with blowing it upwards, thus temperatures will increase!
- This is very unlikely to happen, but if the fans were able to move vast amounts of air out of the rear of the case (which if it's hot, it will just rise anyway), the temperatures would decrease (impossible to achieve with my case and probably the most pointless thing I have ever said).
To conclude, in normal environmental situations, I'd suggest positive airflow depending on your case. I wonder how long it will take before companies start making fridge cases more accessible to the public as it's not exactly easy to get hold of haha!
Could just mod one I suppose, would that even work? Hmmm...
Another afterthought, you guys have obviously heard of oil cooling, what do you think of that? Other than totally not worth it.
