I've been looking into getting a new case lately, because my AMD Athlon 64 3000+ is idling in windows at about 62C, I have a 3-4year old Antec Full tower ATX case, no side panels, 4 case fans 80mm I believe (2 front intake, 2 rear outtake), and a Thermaltake Polo 735 CPU Heatsink.
My Case temp is about 29C currently and it is fairly cool in my room atm, when summer comes around I'm worried it won't keep cool enough anymore, recently my Computer wouldn't start up cause the CPU was getting too hot when windows tried to load, I opened it up and there was alot of dust buildup on my Heatsink, I cleaned it off, and also removed, cleaned, put in new thermal paste, and reset the HS. But my temps are still 62C idle, and get up to 69C under heavy load.
I was wondering if it is likely my case, or my Heatsink, or both. I just bought the Polo 735 with my Mobo and Processor a few months ago, and I read a review about it recently which gave it a good rating, so I don't see how it could be that. Would Artic Silver 5 Thermal Paste help alot?
If I do end up getting a new case it would be around 100$. I was looking at this case
, but any other suggestions would be appreciated. Does a side panel fan help alot? I'd like to get my CPU down to like 40C which I have seen others say they get. Or could the problem just be that the CPU itself is running hotter than it should? Thanks for any help.
BTW my Thermaltake Polo 735 is currently running at full speed (5500RPM), and it does get slightly hotter when I turn the fan down.
