Clean off thermal grease when changing mobo?

I will be swapping out my motherboard for a new one.

There will be about 10 days between the time I take out the CPU from the old mobo and the time I get the new motherboard.

How should I store the CPU and heatsink for those ten days? Do I need to clean off the thermal grease and apply new one?

The CPU is i7-2600K with the stock Intel heatsink and fan.

It's only about a month old.

Simply clean off the thermal paste from both heatsink and CPU with alcohol and a lint free cloth. Store them anywhere that is easy to find and will not be accidentally damaged. I put mine on a bookshelf.

Sometimes the heatsink is stuck to the CPU so I normally turn on the PC for a few minutes to heat up the thermal paste, then switch off the PC before taking it apart.

Ok, that means I have to buy thermal paste, right? Should I just buy a fan that comes with thermal paste?

Nikorr, you use the coffee filter to clean off the paste?

I am RMA'ing the old board, and expect it will take 10 days for roundtrip. I did keep original packaging of CPU.

Storage And Clean-Up - That is the way I do it : )

To keep your new thermal compound fresh for future applications, always replace
the cap on the syringe after each use. The syringe should be stored tip down so
that any separation between the particles and suspension fluid will be at the back
end of the syringe. Like any mix of particles that are many times heavier than the
suspension fluid, there may be some separation in the compound over time when
stored in the original syringe. Storing in a cool place like a refrigerator will
minimize the possibility of separation over time. This does not affect the
performance of the un-separated or remixed compound.

Removal From Hardware:

Thermal compound can easily be removed from hardware using the proper
cleaners and tools: For general clean up, a cloth or paper towel will work well.
Intricate cleaning can be accomplished with Q-tip swabs. An old toothbrush can
often get the compound out of crevices that other tools cannot reach. Again, use

ArctiClean 1 and 2 or high-purity isopropyl alcohol.
CPU Core: Remove thermal material with ArctiClean 1 and 2, a xylene based
cleaner, (Goof Off and some carburetor cleaners) or high-purity isopropyl alcohol
and a LINT FREE cloth (a lens cleaning cloth or coffee filter). If you use Goof
Off or another xylene based cleaner always follow up with a cleaning of highpurity isopropyl alcohol.

Heatsink: Remove thermal material with ArctiClean 1 and 2, a xylene based
cleaner, (Goof Off and some carburetor cleaners) or high-purity isopropyl alcohol
and a LINT FREE cloth (a lens cleaning cloth or coffee filter). If you use Goof
Off or another xylene based cleaner always follow up with a cleaning of highpurity isopropyl alcohol.

CPU Ceramic Package: Remove thermal compound with ArctiClean 1 and 2, a
liquid dish soap (not dishwasher detergent), WD-40, Citrus based cleaners, xylene
based products (Goof Off, some carburetor cleaners and many brake cleaners.) or
mineral spirits. Once the majority of the compound has been removed from the
ceramic, small patches remaining on the ceramic package can be 'erased' with a
soft eraser.

Removal From Self:
Wash your hands with any liquid soap (Dawn, Lux, Palmolive, Etc.) rather than
hand soap. (Do not use detergent for an automatic dishwasher.)

ok, I've cleaned the thermal paste off the CPU and the heatsink, and stored them both in the original box.

Now show I get thermal paste or a new better heatsink that comes with paste?

The thermal paste will clean off easily with isopropyl alcohol and I would clean the cpu before you remove it from the MB so as to not be touching the pin side of the cpu and carefully set it on a soft cloth where it won't be diturbed.
The heatsinks will come with either thermal compound preapplied or they will include a small tube of it for you that will be good for one application.
If you choose to buy some thermal compound then a good choice would be Artic Silver 5 and you can apply it with a small piece of plastic like a credit card and spread a very thin layer , you don't need a lot and too much will defeat the purpose of the thermal compound.

^no, the evo's heatsink doesn't look like that. That's for the 212+.

Use the dot/spot method, worked fine for me.
