I have just brought Thermal paste for my CPU. I applied properly so that you can't see the surface. I didn't let it dry. When I turned on my computer, It worked for about 6 minutes then shutdown due to it being too hot (100+C). The CPU itself is fine, and I had just brought a new motherboard, RAM, GPU, PSU etc.

Do I need to let the Paste dry before working my computer?

No, you don't let it dry. Perhaps you applie too much paste. Also, reseat the heatsink and make sure it's in properly.

EDIT: You do have a heatsink/fan on it right?

[Nikv]

We do have a heatsink/fan on.

How much should I have put on? I put on most of the tube..Would it really make a difference?

After letting it cool down, I booted the comp and it already was in the 100's C for the CPU temp..
It wouldn't take that long to heat up would it? The CPU itself is pretty hot though.

It makes a huge difference, too much paste and the heat will not get transferred to the heatsink to be dissipated. Normally, we use a dot in the middle about the size of a bb, or a line in the middle about the size of a grain of rice. It just needs to cover the processor with a very thin layer.

Read these instructions (even if you're not using the same brand of paste.)

Thanks.
Shall we use the scraper tool they gave me to clean it off?

[+jeston]

Yes, it would be a good idea to clean it all and start over. I hope this solves the problem for you!

You're supposed to put a small amount on, like the size of a grain of rice, too much and it turns into an insulator (so it keeps the heat in the CPU)

@ title, its called thermal paste, not thermal crust

and i put on quiet a bit more then a 'bb' when i did mine mabye thats why there wasnt much of a temp difference lol

[Nikv]

I found out it was the heatsink that wasn't on properly.

[zeroday]

All you need is a tiny amount, like a grain of rice, and then use a flat and thin object (a blade?) to spread it carefully. It doesnt need to dry.

[Shof]

what kind of paste are you using?

[Hexter66]

I have put too much on myself and it got stuck like glue between the cpu and the cooler, when I removed the cooler the cpu got pulled out of the sockets. :lol:

then the fun part is getting the heatstink and the processor unstuck. One time, i used a small flathead to pry it loose, when someone else happen

That's what I did once. Took a flathead screwdriver, stuck it between the two, and popped the processor off. Except it sounds like yours didn't work afterwords, whereas mine worked fine.

For my current computer, I probably applied too much thermal paste, since I'd never done it before, but the machine is running rock solid, so I guess it turned out OK. I just made a light spiral from the outside in, so the weight from the heatsink would spread it out evenly. Now I know to put a BB sized dollop on there and use a credit card or something to manually spread it out across the surface of the CPU.

[Hexter66]

Mine worked quite fine actually, except I used a kitchen knife to get the cpu unstuck, when I put the new cpu cooler on, it had the thermal pre applied so I shouldn't have any problem about it really.
