back to fan tests I got the expensive noctua 3000 rpm  pwm fan

it is now the push fan

silverstone pull:

btw the way both noctua and silverstone prices went up on amazon. 

this is now more then 24 + 24 = 48 dollar mod.  there are better fan choices price-wise.

Just put it in and all sound problems are gone. 

I found a really good deal on ebay five minutes ago.

http://www.ebay.com/itm/Delta-AFB1212SHE-Computer-Case-Power-Fan-120X120mm-Lot-of-5-/191443200211?pt=US_Computer_Case_Fans&hash=item2c92e768d3

5 fans for 29 + 12 = 41 bucks  they are pwm   meaning 4 pin  speed control direct plug into the s-5   

 2 of these would be nice for an s-5.

 I  just ordered 1 set of 5 fans.

Keep in mind those ones are the 150CFM version, not the 240CFM AFB1212GHE. It is a good price though, especially for one ready to go with long leads and the 0.1" 4 pin connector.

I used a 3 pin fixed  speed delta  which was  about 148cfm ran at 2800 to 3000 rpm it was a decent  fan purchased  form the same ebay seller  months ago. it was louder then I liked.  these on ebay will ramp up and down if clocked higher or lower at 8 dollars each two of these would be decent.  they will cool as well or better then the silverstone or the noctua will cool.  they will be not as quiet as the silverstone/noctua

they will be much quieter then the  stock fan.  since I order them from the west coast and I am on the east coast .  I may get them for monday.
I purchased them to help buyers find the best fan compromise ... at  8 bucks each 2 for 16 just clip a tiny piece on the fan connector and they will plug right in.

  I think a lot of people would like this better then the stock fan.  and at 16 bucks an s-5 pretty cheap much cheaper then 2 silverstones or 2 noctua's.

klondike_bar's idea of a fixed speed to the stock fan is a possible work around.   

If anyone's interested in really pushing it, I have a pile of these TFC1212DE 250CFM monsters (or their Nidec equivalents), along with a bunch of the 25mm deep 150CFM FFB1212SH Deltas that I don't need anymore. Not all have the 4pin ends.

no wars over the gear please.

be nice to one another. 

Thanks for your answer! I have read your review of the Sp20 and definitely it's a close call. I can find an adapter, so i an try that.   

In matter of prices the best option it's the sp20 group@500$ each w/free shipping but its no longer available. So my i'll see my chances with S5. It cost about 510$ w/shipping to my country.

I'll Keep looking for mod, i think that 60 dB it's fine for me.

 With the noctua + silverstone  cooling is a little better then 2 silverstones.

I now have the gear running at freq 381  hashing at 1251 power is 621 watts or .496 watts a gh   sound is decent.

 I opened a bedroom window to let in some cooler air.  

 the 381 freq stat are below

they are pretty good….

 now if the cheaper delta's from here:


http://www.ebay.com/itm/191443200211?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT


do the trick sound and cooling wise. I hope they cool better then the noctua/silverstone's cool.  I hope the sound is decent.


  I would then rate the s-5 tied with the sp20

my ratings now are made with:

 2 s-5's shipped to my home for 900 + 74  to mod fans = 974-----note the fans I picked went up to 74 for two machines.

 hmmm I wonder if amazon reads this ?

2 sp20's shipped to my home for 1000 + 0 no mod = 1000 .  

 this would change if the price of the fan mod was dropped to 32 not  74 .  making 2 cost  932 not 974

  any way you look at this it is very close and your setup in home will matter.
