The fan on my GTX 560 failed and rather than replace the entire heatsink with a new fan / heatsink combo I just wanted a new fan rig. All the other fan replacements looked cheap so I went with this. With the stock fans the card still overheated. I replaced them with some 70 CFM fans and the card ran ok, but was at 90 c under load. I''m looking into modding this thing now to support 38mm fans and getting a 250 CFM 4pin fan for one of the slots and pug it into the cards 4 pin connector to let the card spin it up when needed. I''ll keep the 70 CFM fan in the second slot.
The best PCI Slot Fan, bar none!

The first time you pick this item up, you can tell it is pure quality. I have used at least two dozen different PCI Slot Fans since ''04, probably more, and they have all ranged in effectiveness from "this is perfectly adequate" to "a flea fart would cool better"...
As I have gone full custom water, my need for any kind of PCI Slot Fan has disappeared, and for the past 3 years I haven''t missed them.
However, I recently added one of my newly-acquired H/W RAID HBA Cards, an Areca 16-Internal-SAS/SATA6Gbps-Port (4 physical ports, with 4x 1-to-4 breakout cables) PCIe3.0 x8 SAS/SATA RAID Controller Card (cache upgraded to 4GB DDR3-1333 ECC and equipped with both a regular BBU and a capacitor and NAND based Backup) to my Rampage IV Extreme. This was to allow me to use the significant number of SAS+SATA HDD''s I already owned as well as those that I was recently given, all while providing far faster speeds than any software RAID implementation AND removing the load from my CPU.
I am running three EVGA GTX680 Classified 4GB cards in 3-Way SLI which takes up a significant amount of space, although the HeatKiller GPUx3 GTX680 "Hole Edition" blocks and backplates cuts the space requirements way down. Also, there is a very high-end sound card (I do audio editing and film editing for work, so this is professional-level equipment) with dual analog/dual digital outputs and up to 192Khz/48bit/14channel output (11.3channel; 7.1 with 2x Front-High, 2x Front-Wide, and 3 total subs instead of 1).
A friend is the head of IT at a large local company, including their 6,500sq-ft climate-controlled Server Room (400 Dual-Xeon boards, 800 8-core Xeon''s, 128GB DDR3-1333 ECC per pair, and 2 Nvidia Tesla GPGPU''s per board), and they just overhauled their storage to include the much faster SLC SSD''s as they have fiber run throughout the building with speeds exceeding 50Gbps and wanted to take advantage of it. So, in went 500 400GB SLC NAND SSD''s and 48 new PCIe3.0 x8 24-port SAS RAID Cards, and out came 325 600GB 15Krpm SAS HDD''s. I was lucky enough to get 25 of them and four fully-loaded RAID cards for as much as the price of this PCI Slot Cooler, total.
As awesome as this deal is, especially as it allowed me to greatly overhaul and significantly upgrade my own home server (got a few dual-XEON boards and 2x 8-core chips from them a few months back, as well as 48x 8GB and 16GB DDR3-1333/1600 ECC RAM DIMMs, LSI CacheCade/CacheVault add-ins for the LSI cards, dozens of different types of internal and external SAS cables and just as many internal breakout cables, two boxes of Delta and NIDEC Server fans, a few 2U and 4U rack chassis, four APC 4000VA UPS units and 8 extra batteries, and a whole, whole lot more). I bought a CaseLabs TH10 for my server, now, too, as it''s the only way to fit all the drives.
Well, it took me all of five minutes to realize that these RAID Controller Cards run HOT!!!!
I first tried just strapping a 92x38mm Delta pushing 114cfm/21.5mmH2O to the heatsink, but the temps didn''t drop enough (~15C drop, wanted at least twice that much). I tried one of my old PCI Slot coolers, an AzenX BlitZtorm dual-fan model, and saw that despite the significantly decreased fan power compared to the Delta, the temp drop was the same!
So, I started to experiment... I tried:
- Removing the Heatsink and applying PK-1 TIM (Result: -4C)
- Applying EnzoTech BGA RAMsinks to all exposed IC''s (Result: -3C plus much better stability)
- Milling a custom "backplate" for the RAID Card via CAD, out of 6.5mm-thick C110 Copper with a layer of anodized aluminum plating on the "top" (looks like HeatKiller GPU Blocks, which I use; Result: -3.8C plus no more bending)
- Replacing the stock Heatsink with a pure-copper 82(W)x88(L)x48mm(H) aftermarket model (Result: -5C)
- Lapping the RAID Chip and the Heatsink and "tinting" them with TIM (Result: -2C)
At this point, I had dropped the temps significantly, but I couldn''t STAND the look of the PCI Slot Cooler and its bright blue ugliness, as my entire build is Black and White, with the red of the MB being used as a "tertiary accent color" very subtly elsewhere. I had spent countless hours sleeving every single wire in the case with 550 and 450 paracord (no heatshrink); I actually made my own cables for my modular PSU using white thicker-gauge wiring (increased one size for every wire) all measured to be exactly as long as needed (and then sleeved it all); I used over 50 of those Mod-Smart 1/4", 2/3", and 1/2" cable tie-downs and a lot of patience (and over 30 hours) to meticulously route every single wire perfectly; I modified my CL TH10 (85mm Extended Vented Top, Pedestal, XXL MB-Side Window, XL PSU-Side Window, and hundreds in other options; custom powder-coated semi-matte White) with C-channel molding around any visible edges/HexxMesh used to cover a lot of internal surfaces and components/actual automotive gauges fit into two 5.25 bays (full-LCD screen gauges that act as both digital and analog; one Water Temp to display H2O temp, one Engine Temp to display CPU temp, one Coolant Temp to display delta-T, and two Boost gauges with one displaying current CPU+RAM Speeds and the other displaying GPU Core/Mem Speeds), custom LED lighting with pure-white LEDs (located behind the MB 1.5CM from edge to create a "floating" effect; behind the reservoirs to make a glowing effect; a pair in each corner of the case shining out to the middle to create even lighting but with dramatic shadows), and using CAD to create a truly custom mount that holds the pumps and reservoirs all together, amongst other things.
Then I saw this. It took me all of ten seconds upon seeing it to purchase three of them and a dozen different 120mm fans to experiment with, thinking that the absolute worst-case would be that it performs similarly to the ugly AzenX unit, but looks infinitely better.
I put the unit in with the stock fans, and I began a one-hour monitoring session (have an Areca ARC-1000BK 5.25-bay RAID Card Controller Panel that will show temp, and I have one of the Aquaero Temp Probes on the chip under the Heatsink).
I was thinking that I had knocked one of the temp sensors half-way off, because the card was reading ~59C while I had 8 instances of an I/O loading tool running, the RAID Card controlling an 8x3TB RAID5 array and an 8x600GB SAS RAID0 array and doing full-speed constant transfers of "full" files between each array and then between the arrays and my MB-controlled 3x1TB WD VelociRaptor Array.
I checked, and the probe was in correctly! I couldn''t believe it! This was with the stock fans, so I couldn''t wait to see what upgraded ones could do...
So I threw in two of my absolute favorite all-purpose fans, the Koolance 120x25/120x38 2600rpm 106.4cfm/118cfm 5.4mmH2O/6.4mmH2O fans. With two of the 25mm-thick models blowing up at the card (an 2.4x increase in airflow over the stock fans), the temps peaked at 51.8C under the same load.
With the 120x38 2600rpm Koolance fans, temps peaked at 50.9C.
With two Delta 120x38 4000rpm 191cfm/25.4mmH2O fans blowing upward, the temps NEVER went over 47.6C!!!!
I should note that, at the time, the GTX480 1.56GB I had in there as a PhysX card was still on air, and with this PCI Slot Cooler and the Koolance fans (which, as always, turned out to be the best ratio of performance:noise), and despite the large RAID Card being in-between, the GPU temps dropped from ~73-75C under 100% load down to 59-62C MAX (OC''d to 945Mhz Core, 1970Mhz Shaders, and 4640Mhz VRAM 145x8, x2, x2 = 4.64Ghz]), so the heat was pretty significant but the case has so much airflow (even if a lot is through rads 4x 560 rads, 1x 420 rad, 2x 360 rad, 1x 240 rads; all have push-pull fans for a total of 38x 140mm and 16x 120mm]), that it would clock high on air without negatively affecting any nearby components. That, and the MB/CPU/GPU''s/RAM all have waterblocks.
ANYWAY....
THIS IS THE ABSOLUTE BEST PCI SLOT COOLER YOU CAN GET!!!
The fans are able to be set in any configuration, blowing in or exhausting out, and you can replace with your own (and even use 120x38 with a small modification).
It''s not the cheapest, but it''s the ONLY one that looks good, and it is FAR AND AWAY the BEST PERFORMING!!!!!!
Great compliment to a single passively cooled GPU

I am using two Scythe Slipstream 1900rpm fans in this, in a pull set-up, directly under my GTX 560''s heatsink (Accelero S1 Rev2 Passive VGA Cooler). Coupled with the Ultra Kaze 3000rpm in the front of my case, my 560 never exceeds 71c with repeated and extended punishment from OCCT.
Great improvement in airflow

I have a Zotac 480 amp edition that I''ve overclocked rather heavily and due to the fact that the cooler pushes air around in the case vs. shooting the exhaust out the back of the case I wanted to increase the airflow in the PCI/GPU area. I have an corsair 800d case and this cooler barely (and I mean barely) fits in my case, it makes contact with the fan shroud of the GPU. For this reason I switched the fans from exhaust to intake so that it''s feeding cool air directly into the card as opposed to creating a vacuum and preventing the GPU cooler to do it''s job well. Since the the length and overlapping width of the cooler is larger than the gpu it helps route more air upwards and out of the case which has top mounted exhaust fans. The cooler flows a nice amount of air upwards and there is a definite increase of air coming out the top of my case now, my GPU, while still getting hot, suffers from much slower heat soak and will run for much longer at full burn before getting hot. This cooler has allowed my overclock to run several degrees cooler and the bonus airflow in the case was a nice added bonus. This mod is large and a little expensive for what it is, but provides a great platform for increasing airflow over your GPU and in your case for that matter. I''m currently in the process of replacing the fans with higher flowing LED fans so I''m sure that will increase my flow even more. Overall I''m very satisfied with this product and just warn people to ensure that they have enough room inside of their case before considering one of these as mine barely fit with my 3 slot wide GPU.
