CPU overheating issue

[thestones20]

Hi, 

 

This is my first post here so please dont judge too hard. Thanks.

 

Okay now the problem:

 

2 weeks ago I noticed how my cpu were constantly overheating in idle about 55° (Celsius) and on full load about 87°. I figured thats not normal and ordered a new cooler (be quiet! BK009 Pure Rock). 

 

I changed coolers and it was all fine! On idle 27° and full load max 70°

 

now, 2 weeks later im having the same issue again only worse. On Idle its most of the time at 60-70° and on full load 85° and up. 

 

Does anyone know whats happening to my cpu? The cooler itself works as new.

 

CPU: Intel core i5 6600k

I dont know, I just used the paste that came on the cooler.

I would reapply the thermal paste like this:

Spoiler

1- Get some thermal paste, I have found artic silver 5 gives the best results, and some TIM cleaner, You could probably go with out, the TIM cleaner that is, it but it makes the job easier. Make sure you have an anti-static strap and your using it, its unlikely to matter anyway but better be safe then sorry. 

2- Disassemble you computer then remove the heatsink.Once you have taken the heat sink off, put some TIM remover onto some tissue, toilet paper will be fine, and gently wipe over the CPU/GPU/North bridge(Select as appropriate). until there is no paste left, not even a trace should be left. If the TIM isn’t coming off easily then you can put some directly onto the chip.

3- Wait 2-3 minutes, this lets the tim cleaner lifts what has been missed. 

4- Wipe all the surfaces you have just cleaned with a material like your t-shirt, a first run of this stage could be done with some tissue then your t-shirt but it doesn’t really matter as long as it is gone.

5- Apply a line of thermal paste in a parallel line to the longest edge on the CPU/GPU/North bridge.

6- Spread it out most TIM kits include a spreader but you can always use some cling film over the end of your finger, I found the spreader easier but your milage may vary; you want a thin layer over the whole die, making sure that you can't see the die, if there is some on the socket latch (or on the green part,Mobile chips) then its not too important but some people may remove it, I personally don’t bother.

7- Place the heat sink down at a one or two degree angle and then turn it so that the mounting holes are all align, then wait a few minutes, this allows the air to escape.

8- Tighten the screws down in a star like pattern, make them all finger tight and then go around with a screw driver, the heatsink shouldn’t move at all. 

9- Make sure that it is all tight and reassemble you computer.

Thermal paste doesn’t last long and should ideally be replaced yearly.

Make sure that the cooler is held down properly and that the case has sufficient air flow.

What about your fan curve, total airflow, dust filters, dust amount

Oh well im not an expert in this but I think its fine (?) It did with the old cooler until recently.

Im really bad at cooling and stuff so I just used the fans my case had

 

Case is: Fractal Design Define R5 Black
