The cooler is available at sharkacomputers.com for $84.90 (cooler + ramsink)

They have 8 in stock.

Someone needs to get this and do a review quick against the HR-03

I'd love to see which one is quieter and which preforms better.....

Thanks for the heads up! A lot of folks have been waiting to see this in action. Looks like it'll only take up an extra slot or 2. Still the problem of exhausting the heat remains, although some users of the HR-03 don't seem to have a problem with this. My guess is the Thermalright HR-03 will be hard to beat in terms of cooling performance. All will depend on which fan you use, the Scythe S-flex E or F.

I just got a confirmation from sharkacomputers.com that they don't have the RHS88 for the 8800 GTX/GTS yet because of the miscommunication at Zalman, USA. But the VF1000 is available for those who have less than 8800 series card. They said the ramsink should arrive any day.

In term of thermal performance, the VF1000 should perform better technically. VF1000 comprises of pure copper (the main heatsink and the ramsink); whereas HR-03 Plus are pure aluminum (main heatsink and ramsink).

We will have to see the review, but I've already placed my order so it won't matter to me much. I guess buy it for the small profile heatsink.

How loud is that fan going to be on the Zalman? I like the memory cooler idea.. I wonder if we can use that with the HR-03? I just pulled the trigger on the HR-03 last night... dang!

While copper is better at conduction heat than aluminium, it is worse at dissipating it! I imagine that in actual use it would translate into needing higher airflow to take advantage of the higher conductivity. The hr03 plus also benefits from 2 extra heatpipes and the potential to work with a slightly larger fan. So I think it will perform somewhere between the regular hr03 and the plus version. This is still an excellent cooler.

Anyone heard back from Sharka yet?

lets not get into this argument again...heat transfer from a surface to air is dependent on the convection heat transfer coefficient. It's the same principle for Al or Cu.

I was on the phone with sharka regarding my order of VF1000. There is no definite date about the VM-RHS88 heatsink, but they just said could be any day. They did say that they have the VF1000 cooler in stock and ready to ship. The VF-1000 can be used for video < 8800 series.

Anyone thinking about Zalman Reserator XT and the GTS/GTX blocks, they have them in stock.

Mine arrived from Sharka today.

And?

How did it work...?

I've got an Evga 8800 Ultra KO on it's way, and I want to know if this is what we need compared to the HR03...

christopher3393 · Post by **christopher3393** » Wed Sep 12, 2007 4:23 pm

i haven't installed it. My intent was to give solid confirmation of availability. I'm building an matx system, which means 4 pci slots. Soundcard has to go in 3rd slot, so I don't think the VF 1000 will get enough air to function well. I'm looking into external DACs so still might find a way to use it.

My opinion? Use the HR-03 if you have the space-- it will be both cooler and quieter than the VF 1000. But if you don't have the space, this is the next best thing.

Here's a review http://www.techpowerup.com/reviews/Zalman/ZM-VF1000LED

No comparison with HR 03 though. 85 $ ?! WTF is Zalman thinking on... a cooler that's 6 months late IMO and their fans are usually bad too.

The big advantage with HR 03 is you can get a fan of your liking, and a 92x25mm is going to push more air at lower noise levels. The bad - it takes up alot of slots.

Lately Zalman have been so dissapointing. Power supplies, coolers etc...

Until I see a review on a 8800 Ultra, I won't make a move with my wallet.

Honestly, to make a review for it with just an 8800GTS sucks...
Informative indeed, but doesn't let me know that for sure this thing can cool down a behemoth 8800 Ultra.

Ninety bucks!! FUCK Zalman!! Let me choose a fan at least.

I agrre that Zalman is starting to suck big time... specially with their own custom fans, which are filmsy and noisy... they think they can get away with the cheap noisy fans by giving a Fan Mate!!

VF1000 is no better than HR-03 Plus. Although people have the opinion about cost but you pay for feature and material. I'm not saying it is better but it is what it is. VF1000 is 100% copper, and HR-03 is 100% aluminum; and copper is more expensive in term of material and manufacturing process.

The VF1000 main feature is that it is small. It doesn't take more than 2 slots.
Another neat feature is that the ramsink is bolt through and secures by thumb screws. Although the fan come integrated, you can mod it and remove the fan. Then attach your own fans and your own strapping materials. I think it could fit 2-80mm fans easily. If you're thinking about buying VF1000 for the purpose of overclocking your GPU, you're buying the wrong stuff. The manual stated clearly that this heatsink is not intended for overclocking.

As for HR-03 Plus, just the heatsink alone takes up 3 slots, adding fan takes up additional slot.

This seems like a fairly pointless product. It takes a bit off your temps... but doesn't exhuast the hot air, it just lets it's circulate in the case. Neither review mentions what happens to CPU temps with it installed.

The stock 8800 coolers are pretty quiet anyway, probably no worse than the Zalman on low.

Such a missed opportunity. If they had just made it twice as high (so it uses an extra slot) and added a shround to force hot air out the back of the case it could have been fantastic.
