Question: How Much Thermal Paste Should I Use?

How long should thermal paste last?

If you’re using low-quality thermal paste, such as the stuff you get with some CPU coolers, it may dry out in two or three years.

A hot-running CPU will also dry it out faster.

Good-quality thermal paste (like Arctic Silver) might last somewhat longer, maybe up to four years..

Should you spread thermal paste?

Remember: the goal of thermal paste is to fill in microscopic gaps on the surface of your CPU and your heatsink. It can be difficult to ensure that thermal paste is spread evenly. Some people recommend (wrongly) that thermal paste should be manually spread across the CPU using a flat hard surface such as a credit card.

How hot is too hot for CPU?

Overclocking temperatures could in theory go as high as 90°C while still being ‘safe’, and the max temperature for many CPUs is listed in the 105-110°C range. But for long-term use, you’re much better off keeping things below 80°C in general and only pushing up to 85°C at the most.

IS 100c bad for CPU?

Unless you’re rendering that long projects 24/7, no, it’s not really bad. Though 100C is a bit high, even under load.

Is it okay to use old thermal paste?

Yes, you could use what you have. It probably still works fine, and as long as it’s not dried out and was stored properly (i.e. at room temperature in the dark). It should perform just as well. That being said, you should highly consider buying new thermal paste, or at least a reasonably priced, decent quality one.

Do I need to reapply thermal paste after removing heatsink?

5 Answers. The thermal paste is there to provide good heat conductivity between the CPU and the heatsink. If you separate the two, it is best for you to reapply some thermal paste (VERY thin layer) in order to maintain good thermal contact between the two.

Can bad thermal paste cause overheating?

Putting too much paste on a socket generally won’t hurt thermal performance, because the act of tightening down the cooler squeezes out the excess. Too little paste is bad, but anything above the minimum threshold will have the same effect once the cooler is tightened down.

How often should I use thermal paste?

This guide suggests replacing thermal paste every 6-12 months. Results may vary, but if you were to keep an eye on CPU temperatures by, say, making a note every couple of weeks or once a month, you’d get an idea of how your thermal paste is degrading as time passes.

Can too much thermal paste kill a CPU?

Too much paste is unlikely to kill a modern CPU. The thermal protections in place are simply too good. But, too much paste can cause your computer to overheat and shut down. … Once, all those pockets and spaces are completely filled, excess paste will cause your computer to heat up.

Is 85 degrees hot for CPU?

Regardless of whether gaming or idle, it usually sits between 40-60C. Under extreme temps it jumps to 80-90C. The thermal limit before continued use damages the CPU is around 95C iirc and the cut off point where it shuts down is over 110C.

How can you tell if thermal paste is bad?

We recommend putting some on a metallic surface and spreading to check its consistency and smoothness. If it has separated, comes out clumpy or watery, then throw it away and get yourself a new tube of thermal paste.

Is 100 degrees bad for CPU?

100 degrees celcius is boiling point. … 100 degrees celcius means you’re overheating buddy. It will thermal throttle and you will have a significant loss of performance. If it overheats repeatedly it might damage the CPU especially if it’s above boiling point.

Does thermal paste affect performance?

Things to Consider When Buying Thermal Paste. Getting the wrong kind of paste will not only increase the PC temperature but it may also worsen its performance. Adequately applying the right thermal gel will keep the CPU/GPU cool without overclocking or overheating.

What happens if you use too much thermal paste?

The point of thermal paste is to provide a medium to increase the thermal conductivity between your CPU and the base of the heatsink. If you put too much, it actually acts as an insulator, which is the exact opposite of what you want. In the worse case scenario, you can overheat and damage components.
