Has anyone else noticed how the heatpipe cooler on the rev3 doesn't really cover the second FPGA? It is short by about 5cm. The center of the chip is covered but one whole side is left open.

I noticed this also. If this heatpipe is really custom made the job wasn't done good.

I'm thinking about putting a metal plate between the FPGA's and the heatpipe. This metal plate should cover the full area of both FPGA's and transfer it to the heatpipe. Maybe this could improve the cooling which is obviously mainly limited by the only parted covered FPGA.

Has someone already done this?

I owe my soul to the Bitcoin code...

I use the prolimatech pk-1 for most everything.

For troublesome chips I use the IC Diamond compound. Considering the tops of the chips are sanded one would not have to worry about the diamond scratching things.

Tuniq TX-4 is discontinued, but you can still get it a few places. It has the best thermal conductivity in real-world applications, but is expensive. Tuniq TX-2 is almost as good, and much less expensive.

I used Thermaltake TG-1, lowered temps by about 3-4*, stopped my single from throttling Grin

Thanks for the great suggestions Wink

MX-4

MX-2

Thermaltake TG-1

Keep em coming.Always good to have choices Grin

Again,I would like to know what you have used on any FPGA.

What heatsink compound have you guys been using as a redo on the singles Huh

Personally, I despise thermal grease. I plan to replace the grease in my mini rigs with phase change material (PCM).

Experience has led me to love PCM for CPU and GPU cooling. Never tried on an FPGA, but I'm definitely going to.

Thanks,but I have grown VERY fond of Ceramique for CPU's & GPU's,for the last 6-8 years,but for these FPGA's I think it's a little too thick.

I'm mainly curious about what folks have actually used for the FPGA's.

So far MX-4,any others??

Please keep the suggestions coming,Thanks Grin

Most people use MX-2. It's pretty much the price to performance king of thermal pastes. I think it's about $4-5 cheaper than MX-4.

Yes, regarding above post, I worked for Securicor and DHL and saw how things are loaded onto trailers, sometimes thrown 2-3 meters forward for it to land hard on the floor, after that half a dozen other heavy boxed thrown on top of it. Only exception is the very top of the range service, for which a great premium is charged but the boxes are handles with more care.
I hope the Mini-Rig has some serious packaging.

I've talked with someone who worked at UPS a while back... same sort of deal. They would laugh at packages that said "fragile" on them, and simply toss them even harder.

Really, that's why you need so much foam and bubble wrap to ship anything safely. I'd say that the BFL units are wrapped pretty well though.

So I received four BFL today in one standard USPS box. (4 BFL, 4 Power Bricks, 4 USB Cables) It was severely dented on all corners. It looked like at lease at least one of them was going to be in a bad way considering the weight of the package. Luckily, I have all four up and running without issue. No dents, blemishes, or pieces rattling on any of them.

To each his own... those are usually the types of pads people try to avoid though! They don't conduct heat very well.

Just NO. Much easier to use but not better cooling.

They won't let me video the "fun stuff" I would assume...

While you're there with your spy-cam glasses, mention to them that they don't need to scrape the top off the chips, or any other 'damage' they do to them to hide what they are, any more.
Maybe that old lady can get more boards completed more quickly that way

Can anyone tell me what's the best way to cool a BFL single with a fan?
I have one of these usb fans: http://www.amazon.com/Thermaltake-Mobile-External-Cooling-AF0007/dp/B002OJN250/ref=sr_1_2?ie=UTF8&qid=1337559123&sr=8-2
I currently have it sitting on top of the single and pulling air upwards. Is that the best way? Or maybe having it blow air in from the side? Or do I need to remove the case for a fan to be effective?
