As I was debating which board to try it out on first, I realized I needed to see the biggest bang for my buck, and so decided to try it out on the DFI Infinity NF Ultra II-M2 (socket AM2) motherboard.
This motherboard is currently busting up overclocks and getting itself into the OC Database here at DFI-Street, but the one disappointing factor so far has been the chipset temps with the stock cooler:
Full Size, Hi-Res version
Full Size, Hi-Res version
Now, I'm not here to bash DFI, but the stock cooler is...mickey-mouse at best. My temps during idle as well as load on the stock chipset cooler have hovered at 60C to 65C, with the average (ie: what I notice the temp is everytime I walk over and look at it!) being 61C.
61C!!!. Blasphemy!
So, I wanted to get something else going on there, and Thermalright had sent me the original HR-05 about a month ago. I have to say that in a single video card situation, the HR-05 (as well as the new HR-05 SLI) is a fantastic little solution.
Very easy to install on ALL DFI LANPARTY/INFINITY MOTHERBOARDS.
I put that in giant bold red letters because I know a bunch of you will ask "but what about this board? What about that DFI board?".
The answer is that it will fit on all of them. NF3, NF4, ATI, etc. It will even fit on the Intel board, but before you jump out of your chair to go buy one, you best just sit tight as that is another story for later on...right now we are focusing on our most popular boards, the socket 939 Lanparty/Infinity series.
Now, as I was saying, the HR-05 and it's SLI brother both fit most righteously on the Infinity NF4 Ultra II-M2 board, and if there was ever a board that needed some better chipset cooling, it would be these boards.
So I dropped the normal HR-05 on one Infinity Ultra II-M2, and the SLI version on another. Here's some pics with both 6600GT SLI, and my trusty X1900XT monster:
6600GT SLI:
Full Size, Hi-Res version

ATI X1900XT Crossfire single-card setup:

Now, what you really want to know...
Stock AM2 cooler:
Infinity AM2 @ 260x10, idle = 61C avg temp
Thermalright HR-05 SLI cooler:
Infinity AM2 @ 260x10, idle = 44C avg temp
pretty decent 17C drop...booyah!
Stock AM2 cooler:
Infinity AM2 @ 260x10, load = 66C avg temp
Thermalright HR-05 SLI cooler:
Infinity AM2 @ 260x10, load = 48C avg temp
scales well...it's busting out 18C cooler at load!
and finally, here's what happens when you drop a silent 120mm fan anywhere in the vicinity so that the HR-05 gets some airflow!
Thermalright HR-05 SLI cooler:
Infinity AM2 @ 260x10, idle = 37C avg temp
Thermalright HR-05 SLI cooler:
Infinity AM2 @ 260x10, load = 40C avg temp
Well, there you have it. I can honestly say that when I first saw the Thermalright HR-05, I was not that impressed. Mostly because I am not really all that fond of passive solutions.
But I gave Thermalright a chance, because they make, in my opinion, the best aircooling solutions on the planet, and on top of that, they are consistent with their quality and especially their customer service and support.
So I gave this a shot, and holy %@#$#@ I was blown away by the temp drops.
For the record, I tried to install an Evercool VC-RE, a forum favorite, and it would not install. Too large to fit on this particular motherboard.
I did however, install the Vantec Iceberq that is also a forum favorite. The problem with the Vantec though, is that temps didn't drop but maybe 1C to 3C overall, in any situation.
I thought maybe I was crazy, so I istalled another one on the other AM2 Infinity, and did a lot of anal-retentive checking to make sure I did it correctly...and I did...and the results were the same...1C to 3C temp differences from a stock cooler.
The Thermalright HR-05 SLI and it's earlier version (simply the HR-05) are both excellent solutions if you can find room for them to fit.
Now...those of you running "short" card SLI, like the 6600GT, you can use the HR-05 SLI version as well as the normal version, as long as your gpu cooler is not interfering on the Infinity AM2 board.
On the Lanparty SLI-DR Expert/Venus, and the ATI RDX200 and CFX3200-DR, you might run into some problems with the normal HR-05 as it really isn't designed to be "out of the way". However, the HR-05 SLI version can be easily used in SLI or multiple video card setups, but again, MAKE SURE THEY ARE THE "SHORT" CARDS!.
Long cards such as the ATI X1k series, and the GeForce 6 and 7 series, it still isn't looking good with the HR-05 on DFI Lanparty and Infinity boards.
ONE THING TO NOTE!
I only have X1900XT Crossfire cards to test with. I do NOT have any of the current Nvidia GeForce6/7 SLI cards to test with. The best I can do for Nvidia at this time is the 6600GT series, which as I have shown you, are very short cards.
If someone has real SLI NV6 or NV7 series cards they can test with, please let me know, and show us some pictures if you can get it to work!
Now, I will throw up some more pictures as I can get to them showing the HR-05 and the HR-05 SLI chipset coolers on various DFI Lanparty/Infinity motherboards, just because I know some of you won't believe my words unless there is a picture accompanying them!
Leave comments and such for me (and Thermalright as they will read this!)
Thanks everyone, and especially thanks to Chris & Hank @ Thermalright.com for allowing me to test these coolers!
