So how hot is too hot?

I'm running my batch 1 and batch 2 units at 350MHz now.  B1 seems to have settled on 47c for temp3, where B2 is at 52c now.  Ambient temperature here is somewhat high (28c).

I have to place my unit right at the mouth of AC vent to make sure temp3 < 50C.

Dude,
Can you tell me batch one unit blue fan is it sucking or blowing cold air like PWMS?
Please take a look at my last post

Blue fan pulls air into unit if I understand correctly

If anyone is interested in power consumption of the different clocks:

300:


325:


350:


375:


I think this is very acurate 

greets,
ebereon

Yes you do i have just checked it and it is indeed. i get confused
10X

ebereon,
Great post about power!

What about hash rate at 375?
I am afraid to test it and as reported there is no big increase performance

[Kuma]

Is the measured consumption for 3 or 4 module Avalon? And what should be the recommended PSU wattage for 350 Mhz and 4 modules?

Thanks!

As you can see, I had it running only 1 minute. It had 180HW errors and ~15 shares. The hashrate was ~76GH... very bad and not healty.

This is for 3 module avalon batch#2 black (stock 750W PSU). Just calculate the Wattage for 3 module to 1 and you know what it will be for 4 module

+1. Iam going to upgrade 3avalons with a 4th module from my 4th unit..... eill this need more than 850w psu?  what psu Is highly recommended

Hmm 720W IMO seems to be too much for 750W PSU in the long term usage.

[elasticband]

325 should be ok on 750 psu?

[Kuma]

325 should be ok on 750 psu?

There is 14% reserve, so that should be OK. But it depends on quality of PSU.

I think 750W is output power of the PSU. Should be ~900W@Wall.

At the moment I calculate 720W@Wall with ~80% effiziency = 576W PSU output. Thats fine I think.

Erm you are right. I haven't realized you measured it on the PSU input. My mistake.

so they should run 350 ok with stock PSU?

[ebereon]

so they should run 350 ok with stock PSU?

Thats what I do

and it won't blow up while i sleep..... lol

[goxed]

The power consumption depends a lot on ambient temperature. My stock PSU consumes 850W at night and 950W during the day.
Upgraded to the Seasonic X-650 Gold 750W, and day power consumption reduced to 870W. All at 350MHz.

can anyone recommend replacement fans for  batch one?

can anyone recommend replacement fans for  batch one?

I am interested as well. These look like they can reach 4000rpm max. Will buy a couple in case one fails.
