Overheating with 2 CPU's

post #1 of 31
Thread Starter 
Hey guys,
I was running some diagnostics this evening and ran a temperature check of my CPU. I have a Intel Q8400 not over clocked. I ran a piece of software, forget the name of it, something Core Temp. My idle was in the 50's Celsius and when I played Black Ops one core reached 101! The others were in the high 90's. I took apart the PC. Took out the stock heat sink and added more thermal paste to the CPU. Made sure the heat sink was firmly in place. I ran everything again and I got the exact same temperatures. I got this CPU brand new 6 weeks ago from digiconcepts. I put my old Core 2 Duo and the idle temps were a little less but the temperature would go up to the about 80 Celsius when I played Black Ops. Can a crappy heat sink do this? A bad motherboard? I just got an EVGA GTX 460 FTW a week ago. If I didn't connect something could it cause the CPU to do this? I just don't know what to do here. I don't want to RMA this Quad unless I know for sure it's the CPU ya know? Any ideas are welcome (:

It's definitely the heatsink. If you're on a tight budget, get the Cooler Mater Hyper 212+. Great Price/Performance ratio. And also, don't use too much Thermal paste. Put about a pea sized dot in the middle and let the cooler spread it.

Also, remember to clean it before you just throw more thermal paste on there. It sounded like you just added it to it, and you want to clean it with alcohol / a towel, then you add the new thermal paste, and like Grandestfail said remember to add just about 1.5 rice size, or a bit smaller than a pea to the middle of the cpu.

And yes, a Cooler Master Hyper 212+ is a wonderful cpu cooler for the price / performance ratio it offers. only about 35 shipped. or if you live near a micro center you can grab it there for just straight up 30 bucks.

Wow, ya think? Man... Ya I use the crappy stock one that came with the CPU. Ok, I think I'm going to pick up a new heat sink tomorrow then. My case has a massive amount of air flow, brand new too with plenty of fans. I was just amazed how high the temps were. I'm so lucky I noticed this now! Thanks for the input (:

You are right, I just put a little more on. There wasn't much on it already but I should have cleaned it like you explained. I'll remember that for next time. Thank you!

have u tryed to take off the heatsink and put it back on ( reseat it )

:/ no way it should be neer those temps @ stock lol. my e7400 on stock cooler not oced load's is about 40 - 50 depending on the day

and oced with a C2Q cooler ( pretty good rly lol ) @ 3.5ghz was like 55 - 60 mostly

Stock cooler should not be that hot!! try reseating it if u havnt already... and ambient temps? :/

How can I reset ? If you mean removing heat sink and putting back on, yes I have. I have not been able to get ambient temperature. How do I get those temps? Btw, room temperature is very cool and my PC sits by a cold open window, it's winter outside (: I think I may just need a new heat sink, not crappy stock intel stuff.
