Old CPU onto new motherboard

post #1 of 7
Thread Starter 
Hello. I was wondering if I get a new motherboard and case, but want to reuse my i7 CPU, do I need to get new thermal paste? Can I reuse my heatsink? Is the heatsink/thermal paste on top of the CPU and I remove both of them together as 1 unit? Or do I need to separate them?

You need to separate them. You can't undo the CPU release lever with the cooler installed.

Then clean off the old thermal paste and install new.

Thank you for the reply. My other question is that I want to install an Intel Xeon on my server motherboard. The Xeon says it does not come with a fan, but the Nvidia GPU does come with a fan. I was told by a friend that I will not need to buy a fan/heatsink for the Xeon because the Nvidia graphics card has a fan. Is this true? If I install the Xeon without any fan/heatsink, will it be fine that way or will I need to buy a fan/heatsink?

And what is the difference between a fan/heatsink? If I wanted to buy one, would I buy a fan or heatsink on the CPU? Or are they the same thing? Or does a fan go on top of a heatsink?

No way, man. The GPU is one thing and the CPU is another, they both need cooling.
Regardless what the GPU is and how it's cooled, you still need to have a cooler on that CPU, whether it be heatsink/fan or watercooling.
You should look into getting a nice quality CPU cooler for that Xeon, brands like Thermaltake, Cooler Master, Noctua, etc.. have much to offer. Also make sure that the cooler is compatible with your CPU and socket.

There's a thing called "Passive Cooling", where you can cool the CPU with the heatsink only and no fan. I wouldn't do it with an Xeon but.

If you run any CPU without any method of cooling, it'll likely reach max temp and either shutdown or burn. So make sure you don't use it before you clean it off, apply new thermal paste and a new cooler. thumb.gif

By the questions you ask I can tell you know little about upgrading a computer.

I would strongly suggest that you go to a local computer store, tell them what you want to accomplish (faster processing, better graphics, etc.) and have them advise you about your choices and then have them make the upgrade for you.

Even though that may cost a little more, it will be far cheaper that making major mistakes by yourself, and you'll get exactly what you want.

All the answers you need are on the forum, even a few YouTube videos could help with applying thermal paste/cooling, there's a lot of myths and ways to do it.

Practice makes perfect, but whatever op is comfortable with i guess.

Yes you can reuse your heatsink, but not the paste because most of it will have dried up.

Take care when removing your heatsink, just twist it slightly clockwise while pulling it off, so the thermal paste wont stick to the cpu.
Dont pull it vertically in one go because it might take the cpu along with it.
This has happened lots of times with members here at ocn.

Wipe off the remaining thermal paste on the heatsink bottom and cpu with some most toilet paper or cloth.
Rubbing alcohol helps remove sticky paste.

You have to buy new thermal paste, search in youtube on how to apply thermal paste on your i7 socket.
I assume its LGA1366?
