My CPU is Seriously overheating!

Ok, let's take things one at a time.

 

For processors, they should not run at more than 65-70 degrees Celsius, most processors will throttle themselves down (reduce maximum frequency) if the temperature goes above that threshold.

For video cards, they're designed to run at higher temperatures and they're more efficient (consume less power when they're warmer). Most will idle at 50-60 degrees Celsius and by design will keep the fans spinning at lower speeds to keep the cards silent and cold enough to stay in the sweet spot.

When gaming, it's perfectly fine for modern video cards to stay all the time at temperatures up to 80-85 degrees Celsius, most video cards will adjust the fan speeds to keep the cards under this temperature.

Some older video cards (like Radeon 4850 or 4870 or 48xx in general) were designed for even higher temperatures, it was normal for those cards to reach 90-95 degrees Celsius and stay there.

 

Thermal pastes are meant to fill empty spaces, microscopic holes in the surface of the cooler heatsink and the lid on the processor, they're meant to be applied as a thin layer and no in excessive amount. For the same reason, it's best to apply the paste as a pea size ball in the center of the processor because when you put the heatsink down on top of the processor, the pea will be flattened and will spread in all directions at same time, and there won't be any air trapped between the metal surfaces and the paste.

If you spread the paste before and then put the heatsink over, there will be "valleys" in the thermal paste layer and when you put the heatsink over the paste the paste peaks will act like glue and the air in the valleys of the thermal paste may be trapped there and decrease the efficiency of the thermal paste.

 

Now as you already found out, thermal pastes only change the temperature by a few degrees. Between no paste and some paste (any kind of paste) there may be around 3-5 degrees Celsius of temperature, but between any paste and a better paste like MX-4, there may be only 2-3 degrees Celsius difference.

 

The stock cooler should keep your cpu below 60c when it's used to the maximum, so if your temperature is often more than that, it's unlikely to be the thermal paste.

My first guess would be that maybe there's not enough pressure between the heatsink and the processor.. maybe you're not mounting the cooler correctly, or maybe the clips are weakened or the plastic is bad on those pins Intel usually uses for stock coolers?

 

If the clips or whatever is used to keep the heatsink down on the processor are somehow weak or faulty, you'll probably have to replace the cooler, but with that processor you really don't need to use a 50$ cooler, especially if you're in a country where such amount is a lot of money.

 

You also shouldn't need more than a couple of extra fans to have some airflow through the computer case, to move the warm air around and towards the top of the case where it goes out.

Yes... it's not just my GPU but also my CPU is also overheating as well. A lot worse too!

it seats around mid 50s on idle and 85-95c on load. (rarely over 95+)

I also found out that my CPU is also throttling as well from 5-25% when full load.

I use Arctic MX-4 thermal compound to resolve this issue. But it's only just a 2-3c different which doesn't help that much. I use the spread method for this.

I have a stock Intel cooler that sets to max RPM. Since my CPU is not overclockable.

BTW my CPU is an Intel Core i7 6700.

Any suggestions??? thanks :)

Delid and remove the cheap Intel adhesive, replace with something metallic.

 

Then get a better cooler

How hot is the room? What case do you have, and is it well ventilated? Are you using enough/any case fans? Edit: Answered while I was typing!

I think the average ambient temps in my room is 35c (because it's summer in my place). and my case is an Aerocool Aero-800

Not everyone wants to break their warranty and risk breaking their processor. There's alternatives that don't screw you if you don't do them properly.

I think you're kinda right there. I think i weakened the pins from my Stock cooler because i keep disturbing the pins. (some times the prong got bent and i use my longnose pliers to fix that). and sure will go ahead buy the after market cooler if i got the budget. thanks for the suggestion :)

Ill just buy the Thermaltake Jing because of reasons :
 

  1. It has 2 120mm fan.
  2. it has a TDP of 200watts
  3. Most people said that it's silent
  4. It's perfect from my color scheme besides the white accents on the cooler
  5. it cost 2 times cheaper than the CM 212X

But anyways thanks everyone who give me suggestions about my overheated CPU. really appreciated :D
