This is somewhat what I am using to reduce the fan speed. They do get a little warm .
The ones I have are the ones that came with all my Corsair Fans.

Looks like they dropped a 1-2 WATT resistor in the power line.  With the heat shrink there is no way for the heat dissipated by the resistor to bleed off.  I'd carefully cut the heat shrink away from the resistor.  I'm betting that would help.

With new heatsinks and thermal paste?  Yes.  The heatsinks did drop the temps a few C... I'm waiting on my next batch of sinks to come in this week and I'll finish.
 

 
 Need to finish off the chips by the ASIC (the bigger heat sink)

After to changing to 350. I fined total time completed is the same a Folding Tasks, None Run at the same time that is.
Wattage went up from 280/300 to 420/430, This is my Windows 7 Rig.

You even changed out the inside fans, WOW! Nice Job.
Oh, For Little ones. Why Did I Not Think of That.
What about the 4 ASIC Chips in front? *One in front of them big chips, not sure if they are capacitors or resistors

I'm speaking of the smaller ones in front of the current heat sinks.  I did the ones on the back side where they were barely covered by the large heat sinks.
 (That one is the black to the right of the pictured heat sink.  The brown ones are capacitors and don't need them.)

I did both as you can see below.

 

After to changing to 340 and 350 on my Windows XP Rig the Cheep Power Supply Kills Over.
Changed to 330 Testing Now, so I will have to get a better PSU then this Coolmax CUL-950B. Glad I got it for free.
This is a good example of a Cheep Computer Part
The only item connected to it is the R-Box and two 80mm Fans

 
Will post data after a few tasks complete.

I have an EVGA 850 running mine... got it on sale at Newegg for cheap... works fine but I've only 2 boxes.  I have two Antminer S3+'s coming in next week.  I'm swapping between mining and coining Bitcoin right now.  I will probably order at least another R-Box after things settle down financially (and I can determine if I can make the Antminer work for Mining @ EVGA also... ;)

To start with yes... but I heard in my research I might be able to turn it to less evil things... I'll find out.  Either way it's a project!

Yes... but.. all the Antminers are built on ASIC's.  I'll either figure out if it can be hacked or say the heck with it... either way it's all good fun and at my age, it's an adventure.  (Beats wrestling bears that's for sure!)

Not sure it's worth it.  I've been doing the eBay thing... Bitmain as I understand it, has started charging some ridiculous rates for shipping.  Not sure I'd go that direction.
 

Nope, they want $150 to ship UPS. Not form me.

Be careful with the c1's, they're not cost effective and apparently not too silent either with that big ol' radiator it's paired with.. If you buy a better one maybe a different story, but still not cost effective especially compared to their s5 they just released. Or even the s3's with new chips.
 
And WT**** is going on with the value of the bitcoin.. if you want to buy btc rather than mine, now is time as they are under 275 bucks on some exchanges..  thanks a lot Josh Garza! Paycoin disaster is clusterf****** the market all to h***! Glad I rode that wave and jumped off at the top! I sold some XPY in DOGE for the equivalent of $30/each... most for about 15 bucks though.. then it all went south faster than the titanic, they found out the guy that owns (Josh Garza) paycoin/GAWminers also bought the exchange coin-swap.net on the sly before it went live and there could have been market manipulation.. it gets major scammy real quick! Amazon denies any involvement, they insist his promises are not only false but would violate amazons TOS.. the bitcoin conference in tampa is getting demands to ban him.. now the things are only worth a couple bucks.. which could also be worth the risk/reward but it looks like the house of cards has fallen..

Bitmain's AntMiner C1 combines two Antminer S3's into the same compact case of the S3

I would use my own water parts. But they are also not supported over on Bitcoin Utopia

Here is a great site for miner comparisons -> http://www.rigwarz.com/ for a new item the c1 is pretty far down on that list for GH/Watt efficiency. The s5 seems to be the way to go, but yes, no boinc on any network miners, so for boinc you have to find usb devices, basically any usb miner seems to work.
 
And for comparing altcoins/bitcoins for profit -> http://www.coinwarz.com/miningprofitability/sha-256/ you generally make 25% more than their estimate (from my testing anyway, like with 2 TH/s it says I should make .025 and that's true if you don't choose your pool wisely, but I end up making .03-.035) 

I don't for .03-.035 I would rather get more Badges and Trophies.
But then you are talking about after you pay your Elect Bill.

Funny that a (Kingwin LZ-850) 850 Watt PSU can power 3 R-Boxes with no problems at 350 yet my XP rig with the cheep COOLMAX CUL-950B can only run at 320, it dies above 320.
I put one of my AX1200 on my XP Rig at set the OC to 350 and running like a charm.
Still in Test as I could not believe that a new PSU was the issue and not may the R-Box or even Windows XP.
 
 
 Coolmax CUL-950B. I DO NOT RECOMEND THIS PSU FOR ANY USE.

 Kingwin LZ-850 are no longer made.
 
 
Now I somewhat know why users are having issue with other hardware like Graphics Cards not working with some Power Supplies
