removing thermal grease off of cpu

post #1 of 16
Thread Starter 
I need to redo my thermal grease. I read online that I should be using Alcohol, but I'm to afraid to put it in contact with the cpu. Before I just kind of rubbed my finger on it to get it off and then scrubbed the stuff off of my hand, is that safe to do again? I have a CM Hyper 212 Plus btw with a i5 2500k.

Alcohol shouldn't cause any harm. I use a cotton swab dipped in alcohol for mine. If you use your finger, you are leaving behind not only TIM residue, but you-residue.

No, don't rub it off with your hand. Your skin is full of natural oils that will stay there between the CPU and the thermal compound, so heat dissipation won't be as quick nor effective.

Isopropyl alcohol and a cleaning cloth (don't use a tissue or anything else that will leave lint behind) is the best way to go. It's fine to get it on the heat spreader, just be a bit careful.

Alright well I'll find the rubbing alcohol and do that with a cotton swab then later, thanks for the help. I put on to much because I thought the little dot in the middle and then spreading it wouldn't be enough, obviously I was wrong .

Use isopropyl alcohol 90% or better and use coffee filters to clean it. Coffee filters leave no fuzz or anything behind.

The TIM doesn't need to go to the edges of the chip. If you were to take the heat spreader off the chip and see the actual CPU it would be surprising how small it actually is. It's just a little square in the center of the heat spreader.

Less is better with TIM.

I'm a total noob at this, so I'm taking your post as this.

TIM = thermal grease

So basically you're telling me to put a small square on the bottom of the cooler and then mount it onto the cpu? I've seen a video where they did that and they rubbed the cooler around a bit onto the cpu and then left it sit there. Would that be right?

I just put a pea sized dot right in center of chip and mount heatsink. The heat will spread it out all by itself.

Spreading it can lead to airbubbles.

This. If you have lint-free wipes great, otherwise coffee filters work fine.

This isn't what you want to do with HDT coolers:

With HDT coolers you need to fill in the gaps (between the heatpipes), then use adjacent lines running between them.
Just like in this guide
