GPU cooler fan replacement

I'm getting tired of replacing fans on GPUs.  So, I am hoping to get some links to some products that any AMD GPU alt. cryptocurrency miners have bought to replace their GPU coolers.

I have thought of a few ways to do this:

1. a.  Use an external manual fan control,

b.  Remove the cooler and use cable ties to attach a replacement fan blowing into the GPU,

2.  Use the same fans but attach them to the motherboard, I use Asrock, to the chassis and power fan connections, and use Asrock's AXTU to control the fans.

So, let's hear it.  Who's already done this and what did you use?

Hi ,
I am wondering if there are Credit Card Processors that accept credit card transactions for businesses that automatically payout to a bitcoin wallet.
Does anyone know of a processor that will do that?

I just heard Alex Trebek ask the question something like "Magic The Gathering Exchange in 2014 had a scandal involving which commodity?"

Is this a problem, or not?

I have 2 open crate mining rigs identical with 4 Sapphire Radeon HD7970s the OC with boost.  Both rigs run cgminer with Win7-64.  Both hash great at about 730 Kh/s at 79 degrees.  No complaints there.  But each rig on GPU 3's card gets about 1 HW error a day.  Is this normal?  Should I try to change anything?

here is bat:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --scrypt -o stratum+tcp://gigahash.wemineltc.com:3334 -u pool user name.1 -p password --thread-concurrency 8192
 --intensity 13 --queue 0 --worksize 256 --auto-fan --temp-target 80 --temp-overheat 90 --temp-cutoff 95 --gpu-engine 1050 --gpu-memclock 1500 --gpu-vddc 1.2 --no-submit-stale -g 2 --lookup-gap 2

p.s. I have undervolted before but I am leaving at 1.2v until HW errors are resolved.

This card is driving me nuts.  I cannot get over 550Kh/s no matter what I do with cgminer 3.5 or 3.7.2

Model number: SAPPHIRE HD Radeon 11197-03-40G

Here is the BIOS for this card: Sapphire.HD7970.3072.120925.rom
bios p/n as reported by AtiFlash is 113-2104XTHY-0B5

Rig is Win 7 64 prof.  4GB 1066 Corsair DDR3 in AsRock 790 Extreme3 MB, Rosewill LIGHTNING-1300, 4 riser cables, Sempron 145, SSD HD.  Rig never gets too hot in crate with huge fan constantly circulating.

Current cgminer config (although I have tried just about everything):

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --scrypt -o stratum+tcp://gigahash.wemineltc.com:3334 -u UUUUUUUU.1 -p PPPPPPP --shaders 2048 --thread-concurrency 10240 --intensity 13 --queue 0 --worksize 256 --gpu-fan 50 --gpu-engine 1075 --gpu-memclock 1500 --gpu-vddc 1.125 --gpu-powertune 20 --no-submit-stale -g 2 -v 1 --lookup-gap 2

I have moved the switch to the 1 setting for flashable ROM on all 4 cards.  I flashed ROM with 3 older versions of Sapphire HD Radeon 7970 bioses, 2 crash and other 1 is no change.  I did this test on GPM #2.

Please advise.  Thanks.

Win 7 -64, was using program earlier today.  Now when I click on the desktop icon.  Nothing happens.
Please advise.

Please forgive my newbiness.  I have successfully created an offline wallet system and am ready to send a payment.  I saved the transaction, loaded it into my offline computer, signed it, saved and have reopened the saved transaction in the online wallet computer.  This is where I am confused.  I am attempting to send 1 BTC to an address and that address shows up under Outputs.  The problem is that the BALANCE of my wallet ALSO shows up under Outputs with an address that I did not enter.  I went to Bitcoin Blockchain explorer, entered the address that I didn't recognize and it said "No transactions found for this address, it has probably not been used on the network yet."

Is this correct?  Or if I hit save am I going to send the balance of my wallet to someone?

Please advise and thanks in advance!
