This Delta fan(240cfm) being used as the pull fan lowered temps from 49 to 40:

The problem is:

- cost
- uses 25w
- noise
- buying adapters for 4 pin

I tried a basic 120mm fan and it made no difference. There must be something between the delta and something more reasonable that will work.

NMB-MAT 4715KL-04W-B40/50: http://www.nmbtc.com/pdf/dcfans/4715kl.pdf.

A few of my ants were shipped from bitmain with these fans (which had obviously seen significant 'burn-in test" time..) before they switched over to cheaper/more available alternatives.

Personally, I find that these things are a perfect balance between noise and cooling capability. In general fan noise doesn't both me; it's the resonance and/or squeal that some exhibit - I've never had a 4715KL which has this particular problem. Loud yes, but tolerable.

Unfortunately it can be difficult to source PWM capable versions of these fans - eBay usually has them for sale by scavengers who loot various retired IT appliances (e.g. PSUs, servers, UPS) that make use of this fan. Not for cheap either - as they seem to be in high demand.

Digikey stocks the standard 3 wire version, and again not for cheap

I just picked up this from newegg. It should help with my ants.
http://www.newegg.com/Product/Product.aspx?Item=N82E16816228067

I just got one of those last week. I have it cooling a room with a FrankenJup and an S1. The room now stays at a chilly 85f, lol. But at least the home A/C can now switch off once in awhile. It was running 24/7 otherwise.

I am not sure about the thermodynamics of it. Where does the heat exhaust go? In other words, does it have windows exhaust? Heat has to be transferred somewhere.

There's a 4" exhaust hose that's left out of most pictures.

This looks great! Does it work good? Do you have any kind of fan at the other side of the tube or just the tube itself?

he needs a fan on the other end. needs to be a powerful fan.

this is a good one.

I have some new ones if you want one.

That (your pabst fan) is a poor choice for this application: too little cfm and axial fans are not suited to moving air through ducts etc.

The tubing might be a grea idea! I just need to figure out where to direct the air to... Cheesy

I have one, it's a great unit. Puts out a ton of cold air.

There's an addon module which allows for network connectivity (e.g. shell, SNMP) and a separate temp sensor which looks interesting - at least at the right price.

I don't think the OP understands that fans don't actually cool the air. Your just mixing the generated heat with the ambient air. The only way to actually cool the air is to...

- Exhaust the heat generated by the miners outside.
- Underclock/undervolt the miners.
- Or add auxiliary cooling such as A/C.

I live in the desert and currently have 3 S1s in my garage each with an additional pull-fan. I won't ever be bringing them inside because I already have a houseful of other miners. I'm curious how long I'll be able to run them before they die. So far we've had temps well above 90 and they continue to run fine. The BFL Singles I had in the garage just started to spew hardware errors so I finally had to shut them down.
