Zalman gpu heatpipe

[R.Rabbit]

what do you guys think about this

?
would a crystal orb be better?

[JasonKosi]

egads that thing is huge...

looks like it could work but I suppose it would depend on a lot of variables (heatpipe optimum temps, case airflow, QC).

[Namagomi]

Yeah, it IS passive, after all. I talked to the people at Plycon about it, and they told me that the Alpha 153U would outperform it handsdown.

[Caffinehog]

Heatpipes are capable of moving a lot more heat than heatsinks or water. The problem is, for them to be able to do that well, there has to be about 70C or more difference between the hot and cold part. Obviously, this situation will hopefully not arise on your video card.

[Fluxer]

See how the heat pipe part of the heatsink is extended and goes to the other side of the card? Well, it looks as if its pretty short since the video card in the picture looks like a Geforce 3. I wonder if it's too short to fit on a Geforce 4... Maybe I'm wrong though.

[R.Rabbit]

no, its gf4 capable, uh isnt the Alpha 153U a cpu cooler? if i wanted the best cooling i'g get a slk800 and a sunnun 50cfm!, so does anyone actually know? or is this just a theory discussion, cus i just want to know what the best is

[Caffinehog]

Haha. An SLK-800 on a GPU? That's WAY too heavy. Try a waterblock on the GPU AND the ram if you want the world's best performanc. Yes, it has been done. Now I haven't seen peltierized video ram, but GPU, yes. Who wants to be a pioneer?

[Alien42]

I don't know about water [let alone pelts!] cooling on a graphics card, I know it can be done, but I haven't got the guts [or money to buy w/c kit in the 1st place & replace stuff if I spring a leak] just yet, but I am thinking about making my own DIY ramsinks. I plan to take a leaf [or should that be fin? :) ] out of the Zalman flower HS book - mini-ram-flowers. :)

Ocsystem is using these on their high end overclocked radeon 9700 samples. those are expensive friggent hings. what i would do though, dispite this things passive nature is give it some 60x10 mm fans to cool those heat sinks. I like this cooler, but that is bloody huge to have to take out eh ;D

[R.Rabbit]

i've heard of ax-7 being put on ti4200's an slk800 wouldnt be too much of a problem you'd just need to support it

[Valk]

thats pretty overkill though, even for the top of the gpu market.. .when a blue orb is enough to keep a geforce 4 happy.... of course, i should not talk, I was seriously considering million a good 1/4" off the base of my chrome orb, drilling it out and silversoldering in a copper core. I was going to mount that on my radeon 8500 as a bit of stupidity. but i have seen people actully cut up a volcano 6cu and use it on 8500's. you know, i have seen way too many stupid mods to gpu cooling, and ax 7 or slk800 wouldnt suprise me, but ill be the slk800 would be almost passive :P

[Alien42]

I think I saw somewhere that Saphire are gonna be putting those Zalman gpu heatpipe coolers on some of their R9700-based cards.

[flixotide]

I just use the zalman NB sinks and a pabst cooler on my ti4400... does the trick very nicely, just about 5-10 c's lower than with the stock heatsink/fan that came with my ti4400...

Temps are measured with compunurse between sink and gpu..

Cheers, Flixotide

I imagine that if you put some fans (dare I say a 8cm Panaflo L1A?) on the cold side, you'd get some better performance while maintaining the noise premise of the cooler.
