Memory - 2x2gb Ripjaws - $40
Hdd - 500gb seagate sata3 - $40

Something's wrong... 80C is far too hot... Make sure your heatsink is installed properly and has an appropriate amount of thermal paste.

Maybe they run hotter when your using the on-die gpu?

 

[taran95]

i reinstalled, cleaned and then replaced the thermal compound. Idles 25c and while playing black ops its arnd 45c. is it still good?

Prime95 test result -
test 1 - 55c
test 2 - 62c
test 3 - 70c
test 4 - 75c
test 5 - 80c
test 6 - 81c
is it normal?

Yes, those temperatures are normal. You're fine. Prime95 puts 100% stress on all cores, something no application or game will do.

Intel Burn Test will make it get hotter though.

81c would be way too hot for my liking. Get yourself an inexpensive aftermarket cooler like a coolermaster hyper 212+.

You won't be overclocking the i5 2400 and you won't be running prime95 regularly just for the hell of it, so I think you're fine doing nothing. When using your PC for its intended purposes, your temps don't even reach 50 C. The hyper 212+ is inexpensive, so there isn't really a huge reason /not/ to get one. It just depends on if you don't mind the mild expense + the time required to remove thermal paste, reapply, and then mount the new cooler. And your benefit will be better temperatures in a program that you will never use.

...and what makes you think he'll NEVER use his cpu at 100% load?

...I bet you said you would never max a Q6600 out either right, you would be eating those words now. Try hooking a Q6600 up to a couple fast video cards and then come back and let us know what the cpu is running at. lol

Of course he'll see 100% load temps at some point, and 81c is too hot for me. If it's fine for you then go for it, it's got a 3yr warranty. lol
