let me know how you make out.
Thank you for your help.Ordered 4 fans and a fan controller and a ir temp gun .
. Do you have some temp readings before and after?
actually there are some photos in the prisma threads I am look for them
2 tubes with antminer fans as push and silverstone as pull

all same topic some on short and some on long(prisma)
Do you have some temp readings before and after?
Will two fans like these provide enough airflow in push and pull config? SUNON MEC0381V1-000U-A99
okay they are rated tohttp://www.soselectronic.com/?str=371&artnum=70310&name=sunon-mec0381v1-a99-mec0381v1-0000-a99#tabs-2
234 m3/h 234 cubic meters per hour needs to be divided by 1.7 to get to cfm so they are 137 CFM
I would use it and the silverstone which is 170 cfm
you will be much quieter then stock and still be moving a lot of air.
you could buy 2 sunon and 1 silverstone.
and test 2x sun vs 1x sun and 1x silverstone
these are moving quite a bit of air , but I used
1 silverstone and 1 antminer s-3 fan with my prisma 1 safely for 2 weeks that is about 170 cfm + 130 cfm
the 2 sunon would be just a bit less air then the mix of the silverstone and sunon

you can do it I found a way. use the silver stone

and 1 of these

but I had the older prisma so I am not sure the silver stone will fit.
if it does not fit try two of the ebay fan.
these fans move a lot of air but at lower noise levels.

There has to be a way because i have 6 prismas and they are driving me crazy .When i spend more than 2 hours in the warehouse where they are located i have a headache.I would not change the fans without advice from somebody with more knowledge.

With prisma I would air on side of caution as far as turning down fans and such. I can understand replacing with quieter ones.
But without a temperature sensor, this is not really the miner to try to use the least amount of fans to cool it.

What would be the minimum recommended CFM and pressure for the pushing fan and the pulling one?
Thanks.
Thanks.
Anyway to dial.down the dB on these dam things without much loss, ever a better quality fan?
2 fans help. this one http://www.amazon.com/gp/product/B00A460TK6/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
and this one
