Update Large review of Finksy/J4bbrwock server psus compared to ATXpsu-photos up

where you buy these psu IBM?
they are cheap?

I got them on USA eBay.

They are now sold out.

Got the Giant Fan, Kilo used for the mod from AMazon today.  I must say it runs very quiet and is very clean and sexy for a Triple x 2KW IBM PSU combo.  Please see pictures below.  However I don't think the 170CM will cut it as the pressure seems a bit too weak for 3 x 2KW PSU compare to 4 x 130CFM fans high pressure delivering 520CFM of air for 4PSU.  This fan should be sufficient if you can keep your ambient temperature at 75 or below.  However,  my Garage will be heating up much higher than that in the summer so I need much more air.   So I guess I will pay a little more and standardize on the 4 x 130CFM Ultra Kaze.

P.S If anyone want the single Breakout board for the IBM 2KW PSU to play with, please PM me.  I'm willing to sell them for 1/2 the price I pay for them as I have plenty extras.  This way you can get to play with the 2KW PSU which I think are pretty awesome PSU.  They're extremely compact and my plans is to stack 4 of them on top of each other and use 4 x Ultra KAZE fans on the side.  I have a ton of different of PSU and breakout boards but so far my favorite have been these 2KW IBM PSUs.  So quiet and dependable.  Also the Ultra Kaze as well as this giant Kilo Mod FAN can be run straight from the break out board without needing to open the PSU.

I think you could use the big fans as push pull on two 4000 watt stacked .

But four scythe will surely work.

With four 2000 waters.

So far I am liking all these psus

The 2880 watt and the 2980 watt are very nice.

They are better suited for the s-7 for the simple reason the s-7 is a loud piece of gear.

I can get the avalon6s to run really quiet with the dual 2000/4000 psu

So depending on what you have in house they all have purpose.

 I think I will just standardize on the 4 Ultra KAZE fans as that will also give me redundancy.  I do like this fan though.  Would be nice if they're lower price as we can always buy 2 as you say Phil.  1 For push and 1 for Pull for the maximum benefit, just at a higher price per PSU for cooling.

I shoul pay you a visit.
Just to here those psu's screaming away!

LOL...  Yes, they can scream.  I've been talking of having french doors to the entrance of the recreation room.  I've actually had plywood there for over a year now.  I'm finally going to Lowe's tomorrow to buy a french door for $411.00 plus tax.  I'll have to pay another $50 for them to deliver it.  I'm not going to put that thing on top of my Land Cruiser.

The plywood does a decent job but french doors would definitely do the job.

Can you really hear them if they're quieter than the S7 or are they quieter but make more annoying higher pitch sounds?  I have a bid on a few to play with.

the 2980 psu's and the 2880 psu's sound nasty

as does the s-7

I can get the 2880's and the s-7 to sound okay.

I need to play with the 2980 more.

[nhando]

Sounds Nasty as in a loud pitch sound or annoying whine?

Both. They sound horrible, you don't want them running in your house without modifying them to reduce noise.

loud high pitched whine

Canceling order.....thanks for the heads up.  I will reconsider them as an option once I move my equipment to the warehouse.

The dual 2000 /4000 is for in house.

I hope to get more avalons to be able to test better.

I think I can use the dual 2000/4000 and the 2980 using the large fan mod from kilo17

[nhando]

I have a good deal via a counter offer on Ebay if anyone is interested, PM me.

2 x 2880W PSU for $33 each plus $27 shipped.   So total is $93 or $46.50 per PSU which is an awesome deal.  The counter offer is good for 1day I believe and I'm "NOT obligated" to buy them.  Just throwing out the offer to any member who's looking to try out what Phil is doing for cheaper than normal cost.

I might go with the double DP2000 for my Avalon (which it is not a lot more cash then an EVGA G2) and I would be able to overclock it.

I'm wondering with my ambient temp of 25-30 (77-86 in the US) what the min CFM I would need to cold them. I might plug one or two SP20 with it also ... so not full load but still. Finksy suggest min 100 CFM.

I see that Phil use two Noctua NF-F12 but they cost another 50$ us for the two but they are 71 CFM. I was looking at two silent fan but they are only 52 CFM ... that won't be enough

Not sure what would be best for me.

they will let the dual 2000/4000 total    run at 4080 watts! I ran 17 amps x 240 volts  for 3 days in a row

[HerbPean]

Thanks Phil !

[nhando]

Can't go wrong with the Ultra Kaze as as you will need the extra CFM for 80+ Ambient temps.   I mount them on the side and with the 4k Board, I can stack them 4 high which is the plan.  Makes cabling so much cleaner and sexier.  Got the recommendation from Mr Phil and I've been loving them since.  So quiet.

Dave,

I'm not sure about using those. What's the duty cycle on them? Car radiator fans don't run 100% of the time the car is on, and I don't think they're built for it.

Thanks for chiming in.  That's why I wanted opinions for this application.  I'm not sure on the duty cycle.  It sounds like I need to do some research. 

EDIT:  If you happen to know of a 12 inch fan with long duty cycle and low watts, please let me know.
