Is it safe to touch a CPU with your finger? - Page 2

post #11 of 30
It's not made of glass man, you can touch the top all you want.

Just make sure those curious fingers of yours don't go under the chip, that's just asking for trouble.

As everyone has said above.

Skin has natural oils that will be left behind that can cause micro bubbles in the TIM.
Its always a good idea to clean the die with alcohol before applying the TIM.

And, if your that way inclined, wear a anti-static strap. Dont want to tempt the fates now

The risk isn't from oily fingers touching the headspreader. The risk comes electrostatic induction frying the cpu itself. It's a long shot, but it's not impossible.

CPUs are not really fragile, especially LGA ones.

Even CPUs without heatspreaders are perfectly safe to handle barehanded. High static environments, or excessive physical force, are the only things that could damage it.

Of course, you want to clean any mating surfaces thoroughly before applying TIM and mounting a cooler.

Let me put it this way....a fingerprint on a CPU is the equivalent of a mountain of grease between the heatspreader and the heatsink. Besides the thermal compound, it's one more barrier getting in the way of heat dissipation.

This exactly

Make sure there is not a single trace of fingerprint on the cpu before applying tim,

You could serve dinner ontop of your cpu if you want but the important part is making sure it's clean before the paste goes on

I've just smeared the TIM on CPU's and base of heatsinks with my bare fingers for about 15 years now. Not a single problem. I always clean the CPU Core/Heatspreader and base of heatsink with isopropyl before I apply TIM with my bare fingers...

Seems a bit counter intuitive, cleaning it, then grubby paw'n it.
