Does heatsink resitting require re-application of thermal paste?

Ok, so I'm going to order another 8GB of RAM soon (2x4GB) to total at 16GB. Anyways, I think I put in the Hyper 212 EVO the wrong way as the heatsink itself is on top of the first DIMM stick. I want to reseat it so the fan is facing towards the RAM, which would free up the DIMM slot and allow for a RAM upgrade. My question is, would I need to reapply the thermal paste? I'm running low and need it for when I get an FX 8320 later this month.

Yes you should use new thermal compound, the stuff is pretty cheap just order some more when you get your new cpu. Better to do it right rather than have it overheat.

yes, you re-apply the thermal compound. You actually want to fully remove all the existing thermal compound than re-apply. Also, it's pretty cheap, like $5. I highly recommend Arctic Silver 5

The easiest option would be to move the fan to the other side. No need to remove the cooler.
Just unclip the fan and clip it on the other side.

Okay, I think I have enough for 2-3 more applications. And it's not the fan being the issue, just the cooler.

Thanks for all your help! I resat the heatsink, allowing for more RAM allocation. I chose to use the stock thermal paste, not my MX-4. The CPU seems to be running a little bit hotter, though I'll only have it that way for 3 more weeks maximum. A little bit of thermal paste also oozed onto my motherboard, hopefully that doesn't come back to haunt me.

how much thermal paste did you use? I put around a pea size amount, I wouldn't think that it would hurt the mobo at all in my opinion so dont worry. Too much paste can cause it to not cool quite as well, but if your still running within an acceptable range everything should be fine.

I use pea size as well, but it oozed a little bit when I was lifting the little "bottle" off out of the case. The amount that oozed was minuscule, about about 1/3 of a pea. I also dropped the screwdriver a few times while trying to get the screws in place, but it hasn't damaged it at all. Max temp after a half hour of Prime95 is 59c, it now idles at about 20c/36c (depends on which HWMonitor reading you use. It used to be 53c max and 20c/31c idle. It isn't too bad, and it'll only be that way for a few more weeks, so I don't really mind.
