My rig:
mobo Gigabyte DH67BL
8gig gskill ddr5 1333
i5 2500k
gtx 480

I just bought this PC off ebay and it has a stock fan. On pretty much all the games ive been testing on which are around 2 yrs old ive been getting pretty bad performance and really jerky fps. Where it will be smooth and silky around 50-60fps until I move the mouse around and it will go into the teens. Also some audio stuttering accompanied by fps drops. This is pretty much the same behavior on all 4 of the games ive tested so far.

I didnt know whats causing this as my rig should run these games on high with ease. Anyway someone suggested I run passmark and I did and saw that my CPU temp is going between 85 and 95c and thats just with a webpage up and typing this response. While my GPU which is known as a power hog is at 64c.

What do i need to do? I am pretty sure that these temps are not good at all.

Get a new cpu cooler!! You could go cheap and reapply new thermal paste but I don't think it's worth it. Intel's heatsinks are crappy, get a cheap cooler master 212 evo.

Step 1 is to reapply thermal paste. Stock coolers are kind of crappy, but not crappy like this. Without looking at the PC, my initial fear is that this is a poorly maintained PC that the previous owner decided to make someone else's problem when it started running hot (though I hope not).

yes, reapply thermal paste, just a thin film though, putting too much is counter effective.
at stock speeds, stock cooler should be enough.

in terms of temps, sandy is actually better than the next ones

I must admit that upon receiving this PC I promptly screwed the fan onto the cpu completely forgetting about thermal paste. Yes I am an idiot. I had the pc on for about a day and did some gaming on it. I really hope I didnt screw the cpu up. Im off to get paste for thing tomorrow.

Can confirm, 95c is almost boiling hot. Unless you're intending on frying eggs, we should fix this.

To start, you didn't say if it was overclocked or not. If it's overclocked, reset BIOS settings to default. If it's not, try reseating the cooler after removing the previous thermal paste and applying new paste.

Tell me after you did both of those things, and I can see where to go from there.

I did not have the cpu overclocked. But read my above reply. I did not apply any thermal paste when i screwed the fan in. Is my cpu done for?

No not necessarily. Many motherboards have overheat protection that can be set in the BIOS, and the processor itself will also have a sensor that does the same job. Just put paste on and don't worry too much about it, tell us what happens after.

I'm a derp for not reading by the way. I wouldn't worry too much. Is it good for the CPU? Hell no. Is it dead though? It's still booting is it not? It still ran for a day did it not? (rhetorical questions) I'm surprised it didn't get hotter to be honest. The SB CPUs have a fail-safe to turn the computer off when it overheats not to mention many motherboards in the SB gen have overheat protection. In other words, if it never got hot enough to trigger that, it's probably not even worth worrying anyway.

"In Intel processors, the core temperature is measured by a sensor. If the core reaches its TJMax, this will trigger a protection mechanism to cool the processor. If the temperature rises above the TJMax, the processor will trigger an alarm to warn the computer operator who can then discontinue the process that is causing the overheating or shut down the computer to prevent damage."

Well thats somewhat a relief because the pc never shutdown or had any of those failsafes activate. The only plus to come out of this is I am quite certain that this issue was causing the bad performance in my gaming tests that I have made other posts about. Because with battlefield 3 i seemed to be having the worst performance and that is a very cpu intense game.

Well a simple thermal paste fix and i will find out tomorrow.

Don't mean to be a jerk, but I think it's a tad bit funny you tried to play games with your CPU running @ 90c. We all learn someway or another, it's just part of life, but it's still a bit funny.

And YES. Running a processor that hot will lag you to all hell. Your performance with Battlefield 3 should be satisfactory with a GTX 480, I can assure you. Should run at Ultra although you might need to turn it down a notch.

You dont come across as a jerk and honestly I am a complete moron for this. I didnt even realize what the issue was until someone sugessted I run passmark tests to see where the problems were. Well i downloaded and ran the program and that was when I noticed my CPU temps all out of whack. This was AFTER the gaming lol. Then I finally remembered I had got this pc and in my haste to get it up and running completely forgot/didnt even think about thermal paste when screwing the fan in.

That makes more sense. Lessons learned I hope.

It will likely fix your issue, but update the thread when you apply the paste just to be sure. Also would like to know if the processor is still healthy (probably is but just curious).

90 is high, but i think the cpu should still be ok (sorry too lazy to google max rated temp)
it usually throttle down or shutdown if the temp reaches dangerous level.

with that said, what is left to do is get a decent cooler (or paste or both), apply (just a little) then test.

i'm @4ghz and i dont even reach 65 if i remember correctly (playing bf4), not too sure but it's not 70 definitely.

That you were *running* the PC at 90 is quite fortunate, actually - you have a solid chance that your CPU managed to live unscathed. Get that paste on before tempting fate again, CPU's generate a lot of heat that needs to go somewhere fast and that thermal paste ensures the heat is being transferred to the heat sink. Your cooler and CPU may look smooth, but there are a large number of microscopic air gaps and the paste has a lot more thermal conductivity than air does.

Hey thanks for all the help everyone! I applied the thermal paste and everything is working silky smooth now! Running BF3 on high settings my fps did not drop below 50 and my cpu temps were at 75c and idle temps are between 50-55c. Its just a stock fan so not that great. I will def look into aftermarket cooling when I consider overclocking.
