New Version (unoverclockable) ASICMiner Blade Overclock Kit - IN STOCK

[sidehack]

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 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

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.

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.

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...

Do you send this kit to Brazil? 

[sidehack]

I can; international shipping will cost a bit more but I've shipped overseas a few times.

[sidehack]

Bump for kits will start shipping in a few hours.

[sidehack]

Got about five kits left ready to go to anyone that wants 'em.

[Ally_Rob]

[sidehack]

Oh yeah, got a handful rollin' around.

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.
