Best cpu cooler for overclocking

H100 can't leak, BTW do not use auto overclocking! They set the voltages too high, which in return can damage your processor. Manually overclock in BIOS.

Have you ever considered an XSPC Rasa Kit?

I have not considered that and thank you i will overclock manually in the bios. Which rasa kit would you recommend

What case and budget do you have?

Nzxt Phantom full tower and no more than 175 probably

You should be able to get the rx360.

I would get one of these bud RS360

RX360

These would be fine as well hope this helps! RS240 http://www.frozencpu.com/products/11743/ex-wat-159/XSPC... RX240 http://www.performance-pcs.com/catalog/index.php?main_p...

I think with those mild overclocks, the 212 would do you well.

If you want one of the best and quietest cpu air coolers, look at the Noctua NH-D14:

Another good one is the prolimatech megahalems.

The NH-D14 is the best air cooling period it also silent it performance is better than any closed loop here a review about it http://www.dailymotion.com/video/xbouvb_noctua-nh-d14-c... also don't buy it from newegg it's cheaper at tigerdirect http://www.tigerdirect.com/applications/SearchTools/ite... $84.99

So those overclocks will not require a water cooling solution. You can indeed have leaks with a closed water cooling solution, I had one originally with an Antec 620 Kuhler, although it was just a small one at first and nothing got ruined.

The Hyper 212+ is a highly recommended cooler because it performs well given a $30 US price. Coolers costing $50 or more will give a little more overclocking headroom, but we are talking a couple of hundred Mhz really. Water cooling allows for slightly higher overclocks and a little more voltage, but that will lead to a lower lifespan for most CPUs.

One thing most people don't note about water cooling is that this will lead to higher system temps since the air coolers typically will also cool the chipsets as well. Many folks will either get active fan coolers for their chipsets or make the chipsets, ram, etc a part of the cooling loop. Higher system temps can also dramatically impact an extreme overclock.

My advice is this, if you are not in love with the idea of having water cooling in your system and a max overclock is not a goal then save your money and get an air cooler. Put that extra money toward a better graphics card.

However if you want to show off your water cooler and really like this idea, then go for the H100 which will perform on the level of the highest cost air coolers and doesn't require maintenance.
