Default Cooling Challenge!!

Alright then, loyal readers and supporters of this project, I would like to pick your collective brains. As some of you do -but more likely do not- know, a Socket F/1207 cooler can have two "mounting pitch" variations. The variations are 3.5'' and 4.1''. To be blunt, those of you that have motherboards with the 4.1'' mounting pitch... you have my condolences - you're pretty much limited to handful of awful dynatron/server-class coolers that scream at well over 40db. Thankfully, the motherboard I've chosen for this project, the Supermicro H8QM3-2, uses 3.5'' mounting pitch. Now here's something else you may or may not know - 3.5'' mount pitch is exactly the same a AMD 939 bolt-thru. I say bolt-thru because the retention clip system differ between 1207 and 939, but the whole spacing and (from what I can tell) the backplate are exactly the same. So with all of that out of the way...

Here is my challenge:
According to my guestimates of the maximum available space for the heatsinks, I can use heatsinks that have a maximum width (width as in up/down size) of 79-80mm. Yup, that small. So the challenge is, can anyone help me find a 939 Heatsink that uses a bolt-thru retention system that is no larger than 80mm wide and hopefully a tower heatsink and orients airflow towards the back of the case? It's a tall order I know, but together we can find it.


If no other options can be found with a tower-style heatsink, any other style will do. However, the 80mm width restriction still applies. "Why?" you may ask, "Why does the width matter if the heatsinks can rise over the Ram slots?" The problem is, the ram slots arent an issue at all. CPU sockets 1 & 2 are directly adject to eachother, CPU 3's socket is very, very close to the top edge of the motherboard (and therefore close to the top edge of the case) and CPU 4's socket is directly beside the PCI-express 16 slot. Tough cookies for me.

Before anyone else yells at me to use watercooling: I did some quick pricing out of a WC kit for all 4 processors that used 4x Apogee GT's, 2x MCR220-Res, 2x MCP655/355's and all the accessories and it came out to well over $600... AFTER Pricematching to other stores via NCIX. So sufficed to say, WCing is my absolute Last Resort.

So, any takers for my little challenge? I'll be sure to thank you & mention you in final build log AND I might even think up of some sort of compensation... but we'll see

Good luck...

Install the HSFs with each other's fins stacked... ;P

You need a HTPC-style HSF: Small, compact.

That is a possibility..... but it has to be 939 bolt thru and preferably have airflow towards the back...

I saw it, but I don't think it can handle the heat dump of the optys.

Oh my. Never on one of my boards... I'd rather mod the case and fit tower HSFs instead. I've looked again at your board pic on page 4, you're sure that 4 HSFs mounted to exhaust towards the top would not fit?
