Looks pretty serious.
Here's a babelfish translation:


I'm not sure it got two heatpipes though.

77.9 x 30 x of 105 millimeters (L x B x H)

Compatibility and orientation will be the main concern.

WOW! That's sweet... and tall... and not going to fit on a lot of motherboards.

If it got only one heatpipe I think they sould have taken advantage of that by keeping together the base with a couple of screws. This would give you the opportunity to mount the HS with an angle, and possibly making more room for the CPU HS. Just loosen the screws and turn the HS a bit.

Well, Thermalright almost stole my idea, except the most important part: their heatpipe and fins are in the middle, while mine is just covering half of the base area, so it can be flipped (make more room for the gfx card).
However, the concept has a flaw, when used passively: long gfx cards obstruct the airflow path (it should work very well with 7600GT, I think).
My calculations of the required surface area showed that 60x60 mm is not good enough, and 80x80 was a bit overkill, so their 70x70 mm is fine.

If it performs as good as it looks, I will switch from zalman.

If only they'd made one like this..
Probably around the same price too once it hits the marketplace.

I think I found my new NB heatsink.

Real question is, how does it attach to the MB, and can a solid connection be made?

I tried another Thermalright with a similar design for my processor, and I could not get it to attach firmly enough to do a decent job. I had to conclude that the mounting hardware could have been designed better.

With any luck, this is just a prototype and the actual base will be circular to allow some rotation of the HS to clear components. I guess the dimple seen in the middle will allow a bar with locator (like the HR-01) to secure it. The bar will probably need two sets of holes to align with different NB HS mounting hole pitches. The lower weight of this HS probably won't give the same problem you experienced TomZ.
Looks pretty

I'd like to see this in a show off with the NB47J. For ~$30US it had better decimate the zalman in cooling ability, after all the $5 zalman is quite capable at cooling NF4's passivley (if a little hot).

Thermalright has some nice stuff, but the premium they want you to pay is too high IMO. Take the V-1 for example, nice cooler, but its nearly twice the price of a VF700 and doesn't come with a fan. Tag on another $8-10 for a nice quiet fan a couple degrees difference over the VF700 just isn't worth it.

This will interest you then.

I'll let you guys know how it performs, I seriously plan on picking this up as soon as it's available. Currently using a NB47J on my K8T890 chipset. It works, but I'd feel much better if it was running 10*C+ cooler. I have a feeling this would be achievable with the HR-05.

Can't wait ff. We will of course expect fully detailed measurements to the 'inth' degree

The way these new NB heatsinks are coming out so fast I think in the future motherboards will have retention brackets for the Northbridge too.

I would hope that most 'enthusiast' boards would in future all be fitted as standard with heatpipe coolers as seen on recent ASUS and ABIT boards.
I do like the the layout of the ABIT AT8 from that point of view (remove the parallel port etc and vent straight out) but wish it had the quality of the ASUS board's heatpipes.

Will do my best.

I emailed Thermalright about this product and they said it would be available "in the week of March the 6th."

... *waiting patiently*

Anybody heard anything new on this heatsink? Hoping it shows up in stores soon.

No sign of it anywhere yet but the MSRP looks OK @ $24.95. If Sidewinder get it and discount it like they do other Thermalright then maybe $20..

If only my pesky graphics card wasn't in the way..

HeatsinkFactory.com seems to get ThermalRight stuff before other vendors do. I recently ordered a different ThermalRight cooler from them, and they did a good job with my order. Customer service was great.

Thanks guys.

It's only listed as having compatibility with Intel motherboards though?

"Thermalright weist darauf hin, dass der HR-05 explizit nicht mit NF4 "SLI" Mainboards kompatibel ist"

Not compatible with NF4 motherboards ?

Ahhh, but underneath the photo's on the Thermalright website it has the Intel & AMD symbols with a tick... Maybe you can only run them on nF4 boards if you completely remove the video card

Yeah, I noticed that as well. I'd assume it's designed for Intel and AMD compatibility, but the Intel chipsets listed are the only ones Thermalright has actually tested the heatsink on? It says that a motherboard compatibility list is coming soon.

That dimple remind me of koolance's chipset cooler mounting system:
da block
mounted

of course intel mounting system would be that annoying hook/clip thing

Nice pics, thanks.

Wow, what a difference. So far the NB seems to be running very cool. Unfortunately I don't have any very scientific measurements for you guys, but I can tell you that the NB47J that was on here previously was extremely hot, 61*C on side of the base. Haven't bothered measuring base temperature yet with the fanless HR-05, but according to the finger test it is only lukewarm, I'd guess no higher than 35*C or so. Am even considering a little overclocking now, something I would never have done with my previous northbridge cooling.

My only gripe is that installation was kind of a pain, but not much worse than any NB heatsink. The dimple on the base is very shallow, so the bracket would come off it very easily while you were adjusting the heatsink or trying to clip it in.

Compatibility (at least with mounting hardware) shouldn't be an issue, as TR included two brackets of different lengths for clip-on installation and one bracket for Intel boards. They also included a pad for small die NB (such as Intel chipsets and nForce4).

Kind of on my way out the door here, so I'll post some pictures later.

EDIT: Measured the base at 38*C.

Pictures, pictures, pictures!!!!
