Can I test boot my system for a couple minutes without applying thermal paste?

Christian McCloud · May 12, 2014

My last motherboard was faulty so I had to RMA it and go through the process of taking the thermal paste off my cpu and taking off my heatsink. I was wondering if I could just do a quick test boot without the thermal paste on my cpu to make sure everything worked well. I would only be doing this for a few minutes at most. Would this be too risky or would I be okay?

As long as the heatsink is installed correctly it will work.

Cpu's are known to go past 100 degrees Celsius at boot. I wouldn't recommend it. Thermal paste bridges the microscopic gaps. No thermal paste = hot hot hot CPU = burning = RMA.

Short answer = No. It would not be safe. Thermal Paste is meant to fill in the microscopic imperfections on the CPU/GPU. In a perfect world we could have direct metal on metal contact between the CPU/GPU and HS. But this is not a perfect world and as such, thermal paste will ALWAYS be necessary!

If you don't have thermal paste on your CPU it can and will overheat within a few seconds. I would advise you to not to power on your PC/Mac until you get some kind of thermal paste on it.

When you apply the thermal paste, only put the size of a grain of rice and screw the HS back on. DO NOT SPREAD the thermal paste, the weight of the HS being clamped down will spread the thermal paste. And with normal use of the computer, the thermal paste will thin from the heat. If you have thermal paste running over the sides of your CPU/GPU then you have used WAY too much!

One thing I noticed here. That is a incorrect statement! The CPU on my ASUS ROG G73JH NEVER gets close to 100 degrees C on boot! If it did the fan would crank up very fast and loud! Mine probably stays below 50C during boot as the fan is never on until the computer is on. (Unless I go to the BIOS.)

What you SHOULD have noticed is he said that when asked if going into the bios WITHOUT a cpu cooler was a good idea.

without a thermal paste not cooler, but

Christian McCloud :

No

Funny that, I never heard anything about the BIOS... :ange:

Sorry, I did not clarify. Bu meaning to get past 100 degrees Celsius, I mean with no heatsink or thermal paste and minimal cooling at a 25 degree(Is that about 70-75 Fahrenheit?) Celsius room.

Ah, now that makes sense. And yes 25 degrees Celsius is about 77 degrees F.
