I'm using an ASRock Z77 Pro 4 motherboard, and an intel core i5 processor.
My build has been lagging or randomly shutting down while playing games, and after loading up my CPU monitor, I see that the CPU temperature is close to or surpassing 100C. I don't want my processor to die in three weeks, and I think it needs a heat sink/thermal compound. Some assistance on picking out some products would be greatly appreciated.
Well there's a fan that came with the processor, but it doesn't seem to be working too well... I mean the fan is spinning and everything, but again, 100 degrees Celsius. Can you explain to me why this cpu cooler will be more efficient before I dive in and buy it?
Your stock cooler should never take you even close to 100c even with a mild OC. I used the stock cooler for about a week when I first got my 3570k and overclocked it to 4.0Ghz and I think the highest temp I saw was about 80c. You definitely have to re-seat that cooler, and to be honest, if you don't OC and don't plan to, you can easily get away with the stock cooler...don't waste your cash. As for thermal paste, get a MX-4, that's generally a solid paste.
Cooler Master Hyper 212 Plus
Cooler Master Hyper 212 Evo
IC Diamond 7
^^^^these are great choices and wont hurt the wallet too bad either, lets put it this way. i have a i7 2600 non k overclocked to 4.2 Ghz and ive never seen the temps go above 58 c while using the Hyper 212 Eco by coolermaster. Also i use Antec Diamond 6 thermal compound and its brilliant, i think it keeps up with the Arctic silver 5, which has been revered as an all around great TIM
Then re-seat it! Problem is that once you do that it's best to apply new thermal paste because the stock one that was on it is too thin for it to be effective a 2nd time around! Have you made sure that the fan speeds are on auto in BIOS, and did you connect it to the 4-pin CPU fan header? Even with lowest fan speeds though it should not be taking you to 100c unless you changed voltages and stuff and you didn't do it too well...
yeah agreed with omnimodis78, apply fresh TIM, reseat and are you overclocking at all? in your bios are the voltages set to "auto" if i remember correctly 1.5 is usually a max for continuous voltage but i could be wrong and it could be more system dependent
