I have an i5 4670k Haswell CPU.
It idles around 35c and during gameplay (mainly FFXIV) gets to 75-85c. I'm using the CoolerMaster EVO 212. This computer is about 15 months old. I just started noticing the fans staying at max a lot more and opened Speccy to check temps. If I have FFXIV open and just tab out of it the CPU goes back down to around 60c. Is this too hot? If so, what can I do to lower the temps?

The load temperature is definitely too high for a 212 Evo.

It's debateable how you should apply thermal paste, and everyone has their preference. Personally, I spread it evenly across the entire surface area of the CPU so I don't end up with any gaps. Thermal paste acts as a heat transfer between the CPU and the heatsink, so if you leave gaps, the transfer isn't as efficient and the CPU gets hotter.

Arctic Cooling MX-4 is my preferred paste.

According to Intel, your CPU shouldn't get hotter than 72C. I'm surprised your temps went up to 85C without shutting your system off. Maybe you should double check the position of your CPU cooler and cleant/reapply some thermal compound on your cpu. I have the same setup and my temps never reach more than 65C.

That's fine. Idle temps are ok. Load temps are on the hot side, but you shouldn't experience problems until they hit 90C. I'm using a Corsair H100i with good case cooling in an aluminium case and I'm getting about 30-32 idle and 60-65 load.

If you have a steel/plastic case, hot ambient temperatures (room is above 75F) and slow, inefficient case cooling, it's possible it could get this hot.

Did you overclock this cpu and check its stability after overclocking?
If no. Load your bios to default and overclock again. This time after you reboot to windows, Run a stress program to check weather the voltage you throw is stable with the clock speed. Run it for at least an hour before gaming.

If not, follow this :

ways and points you should consider. [PERSONAL EXPERIENCE]


*Re-apply an aftermarket thermal paste. Arctic Hi Density is an example. Check for videos on youtube on how to remove the thermal paste applied in your cpu.
*Make sure that there is no obstruction of air inside your case. Keep in mind that your cpu needs to breath fresh air inside and breath out warm air outside.
*[RATHER QUICK] If you're on windows 7 / 8. Close programs, background processes like Antivirus or other Processor hungry programs. Reducing the load in your CPU would gradually decrease temps.
*[RATHER QUICK] Give your rig a rest, srsly. :)

hope it helps

No the CPU isn't overclocked. This was the first PC I built and when i applied the thermal paste I felt i may have not done it properly. I dusted it out a few days ago and it doesn't seem to dusty. I'll try the clean/reapply of thermal paste.

Let me know if I help you out.
I think the culprit of overheating issue is the wrong application of thermal paste.
It should be at small amounts, a size of a corn bit or rice grain.

I've seen several videos about how to apply. Some say to smear it around to evenly coat the CPU and others say to depress the heatsink against the CPU to naturally disperse it. Suggestions? Also any recommendations on what brand of paste and proper removal of paste (never removed thermal paste)?

So a bit of an update.... I got thermal paste and replaced the thermal paste... Turns out the plastic "remove before use" label was stuck on the bottom of the heat sink between the plate and heatsink bottom for 16 months.... I idle at 20c now .... all is good

I now run at 40c cpu with ffxiv running. used to be 70-90c while playing ffxiv.
