Would like to lower my temp (57c idle)

CPU AMD athlon x2 4400+ 2.3 ghz
GPU Geforce 8600 gt 512mb

Case ThermalTake WingRS 100 http://www.newegg.com/Product/Product.aspx?Item=N82E16811133048
Cheap Sony DVD drive

Stock Heatsink and fans. No thermal compound.

Anyway the gpu is running around 57c on idle according to EVGA Precision software, with the fans on max while the core temps are 21 and 24 idle. Only a 3 degree difference with the fans turned on auto...Sometimes gets around 75+ when playing games for awhile. Just opened up my case and cleaned it out a bit with some compressed air and cotton swabs (q-tips) but there wasn't much dust in it. There are a lot of extra cords lessening the airflow, but I'm not sure if there's anything I can do there. Any help would be greatly appreciated.


Will probably be buying a 120mm fan to replace the cases and another 120mm for the front of the case.

Thermal compound either the Arctic silver 5 or the mx-2. Probably a better PSU also, any recommendations for a student? (can't spend too much on it).

Also should I get a CPU fan/heatsink to replace the AMD stock one?

Yes, right away. Also, I hope you meant that you only used the thermal compound that came with your stock cooler. Using none at all would be a very bad thing.


...wait now I'm a bit confused. You are mixing together CPU and GPU temps. Is the +75 for your GPU or CPU?

75+ for the GPU according to EVGA Precision, CPU says 20/25 idle according to Core temp. Any recommendations for the hsf?

 

[Proximon]

20/25 idle core temps are basically ambient room temperature, unless your room temp is like 58F

Don't mess with a good thing.

Alright, what about the gpu. Is that normal temp to reach low 80s sometimes 90s while gaming?

For that card I'm not surprised. Could be a bit warm, but then I bet you are really stressing it.

If you wanted to upgrade the card, these are good deals with ideal cooling solutions:

Yeah, it's being put through it's passes for being an 8600. Thanks for all the help Proximon. I'll probably replace the gpu with that EVGA 8800 512mb or the 1gb version for $40 more. When I do that I'll definately get a front fan though.
