My GPU currently sits 1 cm below my CPU's heatsink/cooler. I'm not sure if this contributes to my problem, but my stock 8800 GTX is showing idle temps of 72C. My new mobo will ensure the GPU is a bit further away from my new CPU cooler. But in case the temps stay the same, I need to find an alternative to a GPU cooler since it would blow hot air towards the bottom of my case. All this so I can try my hand at overclocking the GPU.
This case currently has a stock 120mm front intake fan that blows air over two 7200 rpm hard drives and towards the GPU. Also, there's a rear 120mm exhaust fan situated under the PSU. My plan is to use the Hyper 212 Plus so that it blows hot air from the CPU directly towards the rear case fan in a push-pull system. Also, I'd like to install the Thermaltake iCage in my top 3 vacant 5.25" drive cages as an intake fan to blow air directly into the Hyper 212 Plus.
Using the Thermaltake iCage, is it a better idea to:
1) Transfer my hard drives to the very top 5.25" drives, blowing warm air past 2 DIMMs?
* Taking out bottom hard drive cage; front fan blowing cool air onto GPU.
2) Use the iCage without hard drives to blow cool air over the RAM and into the CPU cooler?
* Keeping hard drives in bottom cage; front fan blowing warm air onto GPU.
I'm wondering how hot the air might be blowing past two hard drives and past two sticks of RAM. The Hyper 212 Plus would act as an exhaust for the RAM's heatsinks, yet it would introduce warm air to the CPU. More importantly, how effective would the stock front case fan be for cooling the GPU? Would this make a noticeable difference as opposed to warm air from two hard drives?
Ah, I suppose a new case is the best option since mine lacks a vent on top. I've already rebuilt my rig, though, and I'm happy to say my GPU idle temps have dropped by 10C. This was probably because my card was right below my old CPU heatsink.
