Zalman VF700-Cu GPU Cooler Review Posted!

Dashken · 24th Jan 2005, 09:00 PM

We have already taken a look at the new Zalman VF700-AlCu GPU cooler. Silent cooling and better performance was what it delivered. But can we get more out of its unique flower heatsink design?

Today, we take a look at the full-copper version - the Zalman VF700-Cu GPU cooler! Let's see how much better it is over the hybrid AlCu!

Good review, much impressed by the revised testing methodology. A very good step in the right direction.

Would like to see a direct review against the Zalman XM80D-HP & say some of the other 3rd party heatsinks, like the AC Arctic Silencer Rev3, ATI Silencer, CM Coolviva etc etc....

nice review. i dont quite understand why using delta result not the actual gpu temp?

btw, 4clcius different from the alcu. not that much.

zy · 25th Jan 2005, 08:35 PM

using delta results..

delta means difference..

so basically they are testing when its idle & load..
the lower the delta .. the better it is ..

Testing ZM80D-HP is going to be PITA, because of the installation complexity, and it will probably vary to much to even consider a good test. I've mentioned that in the review. So I didn't bother testing that.

If I have the other coolers in hand, why not?

But testing coolers can be time consuming, but I will try.

We are actually worried about the test results being hard to analyse.

Yup, zy has explained it. GPU temp doesn't mean a thing if the ambient temperature (or case temperature is high).

We will try to make it easier to understand in future articles.

I concur with the new method being better.

To make it really good I'd like an even better description of the computer used, including case and case cooling.
Also a table presenting
- room temperature near the case air inlet. (Standard thermometer.)
- temperature at the GPU fan intake. (Temp probe.)
- temperature at the CPU fan intake. (Temp probe.)
- GPU temp. (Native graphics card measurement.)
- CPU temp. (Native motherboard measurement.)

With these data one could see what effect the various VGA coolers have on the general cooling of the computer. Improved cooling of the graphics card might lead to a warmer CPU if the same air is used to cool both or if the airflow past the CPU fan is reduced.

A conclusion/suggestion in a review might be:
"By all means; if you want a silent and cool GPU use this cooler, but consider improving your CPU cooling or case ventilation to tackle the warmer air."

Cheers

I'm not sure if I want to measure the CPU temperature since this is a GPU cooler review. Other than Arctic Silencer coolers, all other coolers shouldn't change the case temperature, CPU temperature because the ammount of heat dissipated from the graphics card SHOULD be the same despite using different coolers, unless of course you have a theory to prove me wrong?

ok. thx for explanation.

yay, new zalman cooler! the ease of install would probably make me get it over the 80-d cooler
