This is my first post here, although I have been using this forum for years and have found most of what I needed with the trusty search button.

Anyway, I’m looking for a lightweight performance cooler for my i7 920. I stress lightweight because I just removed my mainboard, which has a CoolerMaster V8 on it, and it is visibly warped.

Previous to finding my board warped I was considering replacing the cooler with something that had a better mounting system anyway, such as the Prolimatech Meghalems. But now I would like to look at something lighter.

CoolerMaster V8: 865 grams or 1.91 lbs
Prolimatech Megahalems: 790 grams withOUT fan

I have considered the Zalman 9900 or 9700 in the past, but I feel the weight to performance for these coolers is not very impressive. I would blame this on Zalman’s trend to create quiet coolers, and since the fan can’t be changed it doesn’t really suit my needs.

Zalman 9900: 730 g
Zalman 9700: 764 g

I’ve seen some good reviews for the CoGage TRUE Spirit, and like it as opposed to something else lightweight like the Thermalright Ultima 90, as the TRUE Spirit can accept 120mm fans.

CoGage TRUE Spirit: 670 g with stock fan

I’m more interested in finding a lightweight cooler rather than approaching the 800 gram range (with fan) with some miraculous mounting system. This is because I don’t care how good your mounting system is, the best you can do is change the way the weight is distributed across 4 mounting points on the board. At the end of the day gravity doesn’t change.

Also I have no interest in low profile coolers that blow hot air onto the mainboard. I know that ignoring these coolers means having a large chunk of metal hanging off the mainboard, which creates more and more stress the further the cooler extends from the board.

This is as far as my research has gotten me and now I’m at a dead end. Any help or recommendations in this area would be greatly appreciated. Thanks!

All of this is exactly true, however consider, if you where to support the "upper" part of the heatsink with a brace or even just a string to the top of the case you would cut the weight on those 4 mounting points in half.

Also if yours is a standard desktop tower type case, its the moment of force on the mounting (the weight of the HS x its length ) creating rotational forces in addition to just the weight due to gravity. Just gravity pulling down would not warp the board, its moment on the top pins pulling them up and the bottom pins being pushed in that likely bent the board. If you put a spring on the string you can actually make the moment work in the opposite direction and help counter the gravity force. Fishing line would be almost invisible. If you case has a crossbar along the length near the top its a 1 minute fix.

Anyway, just tossing that out as a cheaper solution than trashing a decent HS or having to compromise on cooling. Its been a long time since Statics class, I might not have physics exactly right but the fishing line works.
 
It's been a long time since statics for me too...

But what about vibrations when I move the rig :) That's when you need those springs.

I've toyed with the idea of fishing line. And the more coolers I look at the more it seems I can't escape the upper 800 gram range for a good OC on air. Might be time to go Megahalems, one 120 x 25 push fan, and a hell of a exhaust fan either at the top of my case for a horizontal HS mount, or at the back for a vertical HS mount. Oh and fishing line.

While I've brought that up, anybody know if a EVGA X58-758 can mount a Megahalems horizontally? Specifically with a 120 x 25 fan on the bottom?

I would think that the fan might hit the south bridge, and the HS would be reaaaaallllly close to the north bridge.
 
My next rig is going to be all water, I'd like to keep this one air for portability purposes. It is temping though, especially with the H70 coming out.
 
the H50 is even more portable then a heavy air cooler dangling from your mobo, I have used the pump (the cylinder above the CPU block) to lift and handle the mobo, it has a VERY secure mounting method and I lug my P180 with it almost everywhere without problems
