First impression: Zalman VF700-CU + 6800GT

mlaw · Post by **mlaw** » Wed Jan 05, 2005 6:37 pm

What is more silent (in idle mode)

The HIS iceq pro 2 solution on a x800pro

or the VF700 in 5v mode

I am thinking of buying a 800pro or XT HIS card, but only if it is a more silent solution than a 6800 GT with a 5v VF700.

any comment is appriciated

I would say the zalman vf700 My X800 Xt is actually the HIS X800XT anyway, and the artic cooler that was on their was making that dam clicking noise....so to me the zalman would be quieter and perform better but that's just my opinion......

I have also just got this cooler to replace the arctic vga silencer and found in my setup it gives better temps and is far quieter

. Only problem I have had is the ram sinks fell off as i didn't clean the ram chips properly but then the ram only gets slightly warm anyway

Okay, tnx for your help

I have decided to get a VF-700-ALCU, and slap it on a 6800 GT (Point of View).

I will post temperatures from it once I get it and mount the VF700-ALCU.

Meanwhile, here is a test of the VF700-ALCU, from a german site . This was made on a FX5800 Ultra, a card as hot as the 6800 Ultra.

Whoops sorry

It is test of the VF700-CU not the VF700-ALCU

My goof

as a side note my sig was out of date I have this cooler on a 6800 GT

falcon26 or nbac (or anyone else)

Do you loose a PCI slot when using the VF700?

falcon26 · Post by **falcon26** » Thu Jan 06, 2005 5:31 pm

Yes the one next to the agp slot...........

Anyone have any results comparing the AlCu vs. Cu only?

mlaw · Post by **mlaw** » Mon Jan 10, 2005 5:39 am

A dutch website tested the VF700 Cu and AL-CU, on a x800pro

The difference in temperature is 2 degrees, both in 5V and 12V.

Link: http://www.tweakers.net/reviews/546/2

They also show that VF700 is a better solution than Artic coolings NV 4.

Also, they get quite a different (better) result, than rojak did ,when he compared the VF700 AL-CU against Zalman old heatpipe solution...
Either Rojak messed up the mounting of the fan, or the VF700 is less effective with very hot card? (Rojaks test was on a 9800pro modded to a XT, a card hotter than the x800pro)

According to that German site, Zalman VF700 produces 37.5 dBa at 5V. I wonder how far they are measuring from?

Anyone got any ideas on why case temp goes down with one of these compared to an arctic cooler?

Im gonna fit this new zalman to a 6800 GT and was expecting case temp to rise

Probably, but I haven't seen it yet

. No difference whatsoever. I also had the GF4200ti/ZM80 combo before.

Adrians rojack pot has a good comparison between the AlCu, Cu and stock 9800Pro cooler.

The VF700-AlCu at 12V and the VF700-Cu at 5V were so close to each other in performance, you can consider them virtually similar in performance. It looks like a trade-off between a lighter and cheaper cooler versus a quieter but heavier and more expensive cooler. You make the choice!

I still miss accurate temp diode readings, but the result is nevertheless interesting. A big difference IMO.

Is the ZM80DHP much better than the VF700-cu at 5v? I was going to get the VF700-cu, but i dunno....

I'm not even sure if the 80D HP will fit my card (BFG 6800oc - Non GT/Ultra)

tay · Post by **tay** » Fri Jan 28, 2005 7:48 pm

As an extremely satisfied owner of a zm80d, I say go with the vf700-cu. Easy to use/mount and more compatible. zm80D is phenomenal with a fan nearby but I Im gonna guess the vf700-cu will be better yet.

I'm planning to get an EVGA 6800 GT PCIe, which appears to be based on nVidia's reference PCB and HSF. Any idea if the stock memory heat sinks can be left as-is with the VF700?

I wanted to do the same thing, but if the memory heat sink is the same as the AGP model you have to take it off.
This is a great product. On my vf700-cu I have the fan set to the lowest setting and after playing WoW for several hours the highest my temp gets is 60. And it is VERY quiet.

Adrians rojack pot has a good comparison between the AlCu, Cu and stock 9800Pro cooler.

Also check out this comparison in german which compares with the excellent aerocool vm-101 and basically confirms that the Cu is the one to get.

ok, either i'm doing something wrong, or my computer is just acting up really badly. i installed a vf-700cu on my 6800gt, and according to nvidia's temperature readings, i'm still around 55 degrees C. according to speefan, however, i'm somewhere around 40 to 44 degrees C. what other temperatures are people getting on their 6800gts?

the reason i'm asking is because whenever i try to play world of warcraft on 1680x1050, i get artifacts everywhere, to the point of non-playability.

to those who are wondering how much thermal paste, if any, did i use, i used the length of a short grain piece of rice, or sashimi rice, from artic silver 5. i put the single pipe cooler together on my 9600xt, and it ran fine, regardless of what i was running.

nbac · Post by **nbac** » Wed Feb 16, 2005 11:18 am

* Did the artefacts appear after the fan swap?
* Are those load temps you are reporting?
* Have you overclocked the card?
* At what speed are you running the fan?
* Did you remove the HSF to see if the thermal compound was evenly spread?

Normal 6800GT temp with stock cooler is 60-75C (according to users on other forums) and 45-55 in idle.
I haven’t tried speedfan, but I believe NVIDIA's drivers will report the most accurate temperature (though I have no proof).

I would try to use a bit more thermal paste. I think early 9800Pro users reported high temps caused by too little paste combined with the slightly
elevated frame on the chip carrier. NVIDIA appear to be using the same frame. It's also hard to measure load temps, since it drops (in my case)
almost 8C the second I press ALT-TAB in HL2.

smoothness · Post by **smoothness** » Wed Feb 16, 2005 5:05 pm

thanks for the reply. i suppose it couldn't hurt to apply more paste. i would think that CPUs would require more paste than a GPU, but apparently i might be wrong.

*there were no artifacts before the fan swap
*the temps i reported were at idle - at load it is 57C
*i haven't overclocked the card
*i'm now running the fan at 12v
*i currently cannot remove the HSF due to the fact that I have inadequate supplies in my dorm

6800 GT with vf-700cu

my gpu @ idle is 55 with ambient @ 40

Sounds strange. I don't think it's a thermal related. Those temps are really good.

Just another thing: make sure not to apply thermal compound in the
area between then chip and the frame as I believe AS is conductive.
The decoupling caps doesn't appear to be isolated with lacquer.

EDIT: Forget what I said about the elevated frame, it's not.
