I replaced the annoying MCP fan on my 680iLT motherboard with the HR-05-SLI. It's working great, my MCP temp is around 55 degrees C under load without a fan and that's with my MCP voltage set to 1.6V in the bios for overclocking purposes.

Experience: 6 Months
Cools extremely well
I bought this to replace the 5k rpm screamer on my DFI NF4 board. From an active cooling solution to a passive one, the temperatures dropped from 50 -> 38~ - which is stellar performance considering my video chokes the air supply to this cooler. Load never exceeds 40 and the 'SLI' designation means it is offset by one PCI slot on my NF4 - enough room for a two slot video card.

High quality build, right angle design, easy to mount
On my Asus Maximus Formula SE MB, the Northbridge was too hot (idle 50C with 1.38v, Crysis load 61C!). I am OCing the CPU and RAM so the there is additional stress/heat on the NB. I replaced the stock syncs with HR-05 SLI and the Enzotech SLF-1 for the SB. This sync cleared the Thermalright Ultra120 on my CPU because of its right angle design. NB now runs 38C idle and 47C load even with increased voltage to 1.40 because my E6750 is running 3.72Ghz and the RAM is at 1161Mhz. These temps are using the HR05 passively - I will be installing a Sunon KDE1207PTV3 70mm fan for better cooling.

keeps my chipset cool, passively
need zip ties to attach fan?
Great heatsink, use it on my MSI K8N Neo4 Platinum (non-SLi), doesn't block any pci slots, keeps the chipset below 40 degrees celsius passively. With the stock one, it was about 45-55 degrees.

No fan nessasary, keeps chipset cool, looks good.
None that I have found
A nice looking cooler, simple to install and will fit several different chipsets, because of the way it rises it can be moved around for best position. You can also put a fan on it if nessasary but I haven't needed to.

decreased temperature by 15 degrees on average...with 80mm fan added.

I actually liked that this product is L-shaped, which allows it to gain some distance away from the video card.
mounting is weak
I just benchmarked the chipset temperature with Smart Guardian at 32 celsius, with the addition of a 80mm fan. My NF4 chipset used to run around 48 degrees average. Great Product, but, as others have said, the mounting is weak. This review was modfied by poster s 11-06-07 07:24 PM

Works VERY well.
Durable, as it has no moving parts.
Can get in the way of other components.
Larger than expected.
Other than taking you computer apart to get tot the underside of the mobo, the installation is pretty damned easy - remember the slap on some AC5, kids!

I sorta lucked out with teh placement, i though i'd have to move it aroudn to fit my new 8800, but luckily it sits RIGHT in front of my 8800's fan, thus cooling my chipset evern further, while raising my video card temps only 3c.

Chipset went from 50c+ with stock cooler, 38c before my video card, and 34c with that fan sitting behind it.

Very neato cooler.. but with that and also-large A4 Freezer Pro, my case is filling up fast.

+Modded Appearance
+Wicks away heat better than stock anything.
+High quality cooling fins.
-Poorly constructed base.
All I can say to you is do not rush into this install. Take your time and plan how your going to put this in without messing things up and causing space problems.

The other major minus is that if your system is running SLI like dual 8800GTX's you won't be able to run a fan attached to it.

Other than that it seems to be doing the job. I have my Q6600 over clocked to 3GHz all stable. It my 680i runing at a smooth 32'C with the FSB at 1.5volts. Before I had this I couldn't get anywhere near this stable of an OC at all without hitting wickedly high temps.

Does not require fan
Great cooling
Does not mount securly
Instructions need improvement
My first 3rd party northbridge cooler. Previously used the stock cooler than came with the ASUS A8N-E. Once replaced, I noticed a big drop in noise and temperature. Problems are the instructions needed better clarification and the mounting is a little flimsy. It has not fallen on me but it moves if you touch it and I wouldn't be surprise if it shifts if you move the computer. I bought it because I was worried the normal Thermalright HR-05 non-SLI wouldn't fit but I needn't have worried. Enough space with a Nvidia Geforce 6600 video card with 2GB ram installed. Good but probably would have been better off saving some money and just getting the normal Thermalright HR-05.

Experience: 1 Days
Cools down my northbridge much better than the stock heatsink + copper piping.
The spring/screws don't hold as tightly as they should, so if you aren't careful, you can shift the HS on the northbridge.

I am baffled as to why they say that this is "SLI compatible". I had to jerry rig my setup just so I could fit one of my video cards in.
Overall this thing does what it's supposed to; sucker keeps my northbridge cool. However, I felt the design of this product could have been better in a few places. It took a lot longer than it should have to install this. I stupidly put it in bent outwards thinking that because it said "SLI compatible" that it would give room for my video card. Boy, was I wrong! Had to spin it around and block my other two PCI-E slots, just so I could free up my other PCI-E slot.

Comment: I was impressed with the HR-05-SLI for both its cooling ability and the flexibility it provides to unique layout issues. Thermalright has always been a favorite of mine with a wide range of cooling products. Introducing the HR-05-SLI after the HR-05 proved to be troublesome in certain setups, shows
