do you think this will work on geforcefx cards?

this is a passive cooler from zalman, do you guys think it will work?

Keep in mind that this an extremely heavy cooler. It's the same cooler that the Sapphire Ultimate 9700 Pro comes with, so if the mounting holes on both cards are the same, I don't see why not...

Wait for other opinions though.

it would be wonderful if it did, since i want a quiet card...

Zalman has not (at least AFAIK) confirmed that the ZM80A-HP can indeed be mounted on FX-cards (or more correctly, that it can dissipate enough heat to be used on a FX).

Sometimes I wish nvidia would actually make some technical documentation easy to find, such as heat dissipation of the chips, maximum temperature etc etc. Would make life so much easier.

As for the heatsink itself, I'm have just bought one to try it out on a 9500Pro. Will see what happens, though there shouldn't be any thermal problems given that the same heatsink is used on 9700Pro in several tests (and Sapphire even manufactures one).

Returning to nvidia, ThermalTake has just released their Giant II heatsink which does contain a small fan. Overclockers Cafe (I think it was) has just tested it, but could not mount it on a FX5200. Unclear if this is an issue with other FX-cards as well.

in fact I really doubt that it will work with 5800 Ultra and not fry your card to death. This cooler has been designed for GF4s and will probably also work with 5600s but do not try it with a 5800 or a 5900!

ahh ok, well aleast lets hope it will work . :cool: . Well i have another question.

will there be a fx5900 128mb and a fx5900 ultra 128mb?

and if there will be two versions, how much slower is the 5900 128mb non ultra?

i have only seen fx5900 128mb, i havent seen any ultras with 128mb yet....

Deimos 06-11-03 11:48 AM

The short answer is yes!. For example Leadtek has a card on it's website that is the "ultra" using 128 MB of memory. Some manufacturers gives me the impression of naming their 256 MB versions "ultra" and 128 MB version "non-ultra", even though they are both based on the NV35 "ultra" core.

Makes me wonder what they will call the NV35 Value that is rumoured.

Anyway, my suggestion is that you carefully check the specifications of the card(s) you are interested in to find out the operating frequencies and amount of memory. You would probably do this anyway, I'm just putting it in print :)

thanks for your answer!

do you think this is a card using th nv35 ultra core.

i think this card seems very nice!

im scared that the zalman might not be enough cooling for the 5900... msi is already slapping a passive cooler on the rear of the board... it sounds like the 5900 is another egg cooker.

lasrer 06-11-03 06:28 PM

ahh i see now that the MSI-card have to be an ultra since it has 850 mhz ddr memory :afro:

stncttr908 06-12-03 08:23 PM

Heh, he was asking about this heatsink and the last thing that came to my mind was the amount of heat these cards produce. Oops. :D

ricercar 06-12-03 10:46 PM

The Zalman ZM80a heatpipe will NOT work alone on a GeForce FX 5800. Notice that copper heatsink covers the RAMs on both sides. DDR2 memories REQUIRE a thermal solution at those clocks, and cannot run exposed. I came, I saw, I fried my stock 5800U in a case with a 59*C ambient temperature. RMA'd a replacement because the RAMs overheated to death!

Consumer GeForce FX 5900 cards ship with DDR1 memories, so you might be able get away with a GPU-only cooler like the Zalman heat pipe.

The FX 5200 and 5600 are fine with a Zalman ZM80a heatpipe.

The Ultra and non-Ultra are the only versions I've heard about so far. What makes you think there's a third option for "value" market? (A Link would be perfect!)
