Nice work Sidehack!

Just some info.  The stock oscillator can be disabled by placing a jumper from pin one to case ground or pin 2, either one.
This pulls the input low on pin 9 of the 7404 hex inverter and outputs a high on pin 8 enabling the four unpopulated pads on the green boards.

So, if people are having trouble desoldering the oscillator, or don't have a heat station, just place the new oscillator on the empty pads and install a jumper.
This will also enable you to slow the clock speed back down by removing the jumper to troubleshoot if need be and also alleviate some frustration with possibly not having the proper tool set.

That's pretty balls. It should be able to cool several 100W blades... Now I gotta think about rebuilding my rack case to hold some of those guys instead of 120s...

By the way, I got the idea of buying that fan, because I just replaced one of those at work. It's used to cool a 20kw AC motor drive. I figured, if it can cool that drive, it should be able to cool a 100w blade.

Yeah that's a beast alright. A veritable ice dragon; maybe I should get some for my backplane? I need to find some more 120mm and 92mm fans from Dell desktops; those things move air like nobody's business.

I though about getting some of those you suggested, but my 1000w p/s (actually 850 at 120vac) is already going to have trouble powering up a full backplane with overclocked blades. The beast, as you call it, is 120vac, and let me tell you, that thing blows more air than a 30 inch stand fan.

And the form factor is kinda rectangular, the heigh is just about the heigh of a blade, two of them side by side should cover an entire backplane.

And the best part, they are relatively cheap.

Now I wish I hadn't bought those puny 90 CFM case fans.

I know. I kept getting more powerful fans.

But the overclocked blades really like their cooling.

After 3 different fan models, I decided to go for broke.

This one cools a bit more than half the backplane board worth of blades.

I only have space for 2 blades left, I'll have to get another fan next time I buy blades.


Cheers

Wow, that's quite a fan. Looks like you should be able to cool several with that guy. I look forward to hearing from you.

I was finally able to properly cool the blades you overclocked. They are on the average producing 30% more than stock blades.

I had to use this to cool them. 12 VDC fans just did not cut it.

300+ CFM, a bit noisy but less noisy that the Butterfly Labs 60GH miner.

I am very satisfied with your work. I'll be contacting you soon to arrange for more blade work.

Cheers

My last few available kits are sold and going out today. I should have a second round as soon as I gather parts, probably in a week.

I ordered these upgrade kits from sidehack and he shipped very promptly.  Got exactly what I wanted.  Now I just need to see if I can make it work.
