is it bad to get thermal paste on the outer rim of the processor ?

post #1 of 10
Thread Starter 
I just built my computer a little about 2 months ago and I changed 3 different cpu coolers and I most of remounted coolers 20 times trying different thermal paste trying to get the best temperatures possible . every time I remove thermal paste and apply it back on I clean the cpu while in the socket I wound up getting thermal paste on the outer rim of the cpu a little got on the green part of the cpu as well is this bad ? also I am getting new thermal paste on Wednesday should I remove the cpu from the socket and clean it off before applying the new thermal paste ? and what should I place the cpu on top of to clean it ?

as long as it isn't conductive it should be okay, and you should always clean off old thermal paste before applying new.

I do remove the old thermal paste I just haven't removed the cpu from the socket to do it but on Wednesday when I get my new paste I want to clean the old paste off with the cpu out of the socket so I can clean off the outer rim of the cpu . what should I place the cpu on top of to clean it off ? or it doesn't matter ? or should I just clean off the cpu while in the socket ?

Some thermal paste is conductive which can short things out. Personally I would clean it still in the socket. The green part of the cpu pcb should be insulated anyways but Im not sure what the copper/gold dots on the pcb are for and would be cautious with that in case you did use a conductive thermal paste.

I normally use Q-tips to clean the sides of the die, then rubbing alcohol and a lint free towel to get the top of the cpu.

All TIM are conductive.... thermally, that is. Only very few are electrically conductive (maybe like 3-4 out of hundreds).


Getting it on the PCB top is not a big deal.
Once again...

What paste? It may or nay not be conductive or capacitive,

Q-tips will usually do.

Be careful removing and reinstalling the CPU, you don;t want to bend any pins.

so dose that mean aslong as the tim was not electrically conductive I dond have any thing to worry about ?

Correct 99% sure your ok, but its always good to use caution. No need to remove the cpu either if your just cleaning off paste.

thanks. I have another ? is it true antec formula 7's performance is better with a overclocked cpu because it handles heat better ? or will I be able to overclock higher with the tuniq tx-4 that I ordered ?

I havent used tx-4 before but am currently using antec formula 7 since my local retailer stopped carrying shin etsu x23d which was my previous favorite. The x23d cooler maybe 1-2c better than the formula 7, probably similar to what the tx-4 formula does from some comparisons I have quickly looked up...

Really its splitting hairs at this level, with your h100i and any of those paste you should get good temps, the problem with the 4770k is that intel used a thermal paste on the die of the cpu core instead of solder so thats partially to blame for higher temps than sandy bridge (2xxx cpu's). Some guys that delid their ivy and haswell cpu's get over 10c cooler temps.

So in the end, of those two just use whatever you already have on hand and apply it in a manor that you get good spread when the cpu cooler is tightened up.

edit:

here is some reading, as you can see temps are pretty close for the most part, it really comes down to the cooler at the end of the day.
