Meghalem CPU Cooler
I'm wondering if the meghalem is the best air cpu heatsink, if not what heatsink will allow me to get the highest stable overclock on my core i5-750. I have great airflow. Also what fans would you recommend for the megahalem or another heatsink
It's certainly one of the best. Other alternative would be tuniq 120 extreme,iceage 120 Boss II, zalman cnps10x, etc. The best bang for you buck though is the hyper 212+ with some high cfm fans like scythe slipstreams or ultra kaze. Take a look at this site for some reviews of heatsinks.
The Megahalems are very good heatsinks. Make sure the heatsink you pick has enough clearance over the RAM chips; especially the RAM which has its own cooling fins. In my case, the Megahalem clip-on fan will not clear the Corsair dominator RAM cooling fins; therefore, I am staying with my CM V8 cooler.

I find that the Megahalems provides the best combination of performance and ease of installation. Seen one review where the Noctua DH-14 topped it by a hair but it's 3+ pound weight scared me a bit and the installation is a bit trying to many. Have also seen more interference issues reported with the DH-14 than i have w/ other HS's.
For moderate OC's (say 3.6) , I'd recommend the Mega and one (1) PWM fan.
For serious OC's (4+ Ghz), I'd recommend the Mega and two (2) PWM fans.
($65 for the HS, $7 for TIM, $11 per PWM fans and $7 for a PWM Y cable splitter if needed).
If that's a budget breaker, look at the Xigmnatec S1283 or one of the others here:

Suggest you avoid the tall heat spreaders found on the Corsair Dominators and GSkill Ripjaws with any of these top end coolers. The Mushkin low profile heat sinks are OK in most instances but, to my mind, most heat spreaders have outlived their function. My son's recent build has the Ascent Liquid Cooler son the Mushkin RAM and they do fit under the Megahalems.
He's running a 920 w/ various separate OC profiles stored in the R2E's BIOS .... the "everyday" profile runs at 3.7 Ghz and has core temps in low to mid 50's....the 4.2 and 4.4 Ghz profiles run 70-74
Avoid common advice about 3rd party heat Sinks when using the mega:
Prolimatech does not condone any type of lapping done to the CPU or to heatsink base. Every Prolimatech's heatsink base is designed on a pin-point scale of how the base is to be flat and/or curved where it's needed to be. We have programed our machines to machine the surface in a very calculated way. Any after-manufacture lapping or modding done to the base will alter the design, hence negating its performance factor as well as its warranty.
Minimal air resistance between fins allowing best balance between noise and performance in range of 800-1200RPM. Above that, it will sound like you live near an airport
If you really want quiet, this is the new kid on the block which doesn't quite matche the Mega in cooling performance while allowing much quieter fans to be used.:
Also note the following author comment on the new kid:
"I can tell you that if you mount this heatsink so it blows air towards the back of the case, you won't come close to the memory."
Here are my views on lapping/polishing.
After reading several articles, and applying my own decisions based on engineering, I decided to polish my V8 heatsink base because it is thick enough to withstand bowing (distortion) due to thermal stress. I decided to leave the CPU alone because the CPU heat spreader is a shallow drawn sheet metal part produced in a progressive die. The expansion and subsequent distortion of the CPU heat spreader can be determined only under lab testing. Therefore, I left the CPU as-is.
As a result of the as-is CPU and the polished base on the V8 heatsink, the temps dropped by 5 to 8 degrees C under identical conditions.
I am aware that some manufacturers put in disclaimer clauses in order to discourage the uninitiated from attempting engineering changes leading to consequential damages including risk to human life. Probably their legal department at work.
Besides, I don't buy products merely based on warranty - if the product is good, I will not need to exercise the warranty. The company's reputation based on its products is what I look for.
