i5 3570k stock high idle temps

post #1 of 7
Thread Starter 
Hi guys, I'm having a little bit of a problem here.

My 3570k is idling around 60oC at stock. It used to idle at around 65-67oC, but I changed the TIM and it's around there now. Weirdly, the GPU is idling at about 50oC, overclocked and overvolted.

Is this still a bad TIM job? Or something else? Where should I begin my troubleshooting?

I see a few different possible culprits:

 

  • The heatsink is too loosely installed
  • The base of the heatsink is not flat enough thereby not allowing a good contact with the CPU
  • The top of the CPU is not flat enough thereby not allowing a good contact with the heatsink
  • The special thermal paste application inside the CPU between the cores and the IHS is bad.  This is why some people are "delidding" their Ivy Bridge CPUs, but it's not because they're getting extremely high idle temps like this.

 

That's all I can think of.

I would add high ambient temps, bad case airflow and the general sucking of the stock heatsink to that list wink.gif Also, what TIM are you using? (probably won't make a very big difference, unless you are using a really bad TIM)

Using MX-2.

Well, are there any troubleshooting steps? And yes the ambient temp is really quite high. About 30oC most of the time, sometimes higher.

Should I even consider buying a new heatsink?

And damn, delidding seems to be sweet. I'm pretty sure it'll void all warranty, correct?

try improving airflow. Maybe a case mod will help.

Also yes, delidding it would be removing the hunk of metal on top of the cpu chip itself, it would void the warranty.

And yes, buying a new heatsink would be a viable option.

Did you clean the cpu properly with rubbing alcohol? Also make sure you use coffee filters to do so, paper towels will leave lint behind. And don't touch it with your hands, the natural oils your body produces would keep heat from flowing away from the cpu.

MX-2 shouldn't cause any problems. And tbh 30° above ambient doesn't seem implausible. When I still used my stock heatsink I was idling at +/-48°c with an ambient of about 20°c. That was a stock i7 860 though, so I don't really know how they compare. Now I am using a BeQuiet Dark Rock Pro 2 and during prime95 it barely hits 48°c on 35% fan speed. So yes, it is worth upgrading!

And yes, delidding will void your warranty...

Yep, I'm sure I cleaned the old TIM properly. Used a lot of qtips and some 90% ethanol. It was very very clean after I finished. Dropped a pea-sized drop of MX-2 in the middle, and remounted the heatsink. Dropped temps by 10oC, so...
