Thermaltake DuOrb vs Zalman VF900-CU (lots of pics)

[PcCI2iminal]

The test is very simple,i just had to stress the card for about 6mins and the results are very impressive


Stock HSF


Stock HSF fan @ 50%
Idle : 52º C
Load : 74º C


Stock HSF fan @ 100%
Idle : 45º C
Load : 70º C



Zalman VF900-CU


Zalman Vf900-CU fan @ 1350rpm
Idle : 39º C
Load : 57º C


Zalman Vf900-CU fan @ 2400rpm
Idle : 38º C
Load : 50º C



Thermaltake DuOrb


Idle : 34º C
Load : 41º C


Thermaltake vs Zalman
VF900-CU It's quiet, quality, easy to install and performs well ,The VF900 is really small especially when compared to the DuOrb, which is about twice as heavy and twice large,well... the Zalman is no contest for the Thermaltake,there s about a 9C difference between them, ,if it's performance that you want, get the Thermaltake

VGA->X1950Pro 512mb

Excellent, i was curious as to how well this thing performed

[LuckyNV]

not bad, I need to know how good it is on an 8800/X1900XT type card, anyone?

[bauer]

Nice job Criminal

The Thermaltake cooler is noisy?

[EnJoY]

Always enjoy your write ups man!

me?
I will buy a new 8800 for gamming and testing

Nice job Criminal

nah ,the Intel cooler box @ 2200rpm+ is worst than DuOrb

Always enjoy your write ups man!

thx bro ,I really EnJoY that job

i have more tests to share.

The case is a Coolermaster Stacker with no air flow and of course is with the side panel closed and the room temp -> 24C



CPU-> Q6700 @ 3400mhz
MB-> DFI RD600
CPU Cooler-> Auras CTC-868
NB-> passive
DDR2 Cooler-> Thermaltake Spirit RS
HDD-> Raptor 10k x 4


ATI Stock HSF


Thermaltake DuOrb



the NB drooped from 62c to 56C and the cpu went from 50/45/44/47 to 47/43/42/43

Great review Looks like slapping on dual VF700 kind of works I've made a graph for those who want to see everything in one shot.

What's the significance of Load - Idle temps?

Delta should be Load - Ambient temps.

Interesting that CPU temps went down too...I can see why though (the card artificially chambers the heat and because the card is physically cooler with the better HSF, it allows less heat to transverse to the CPU area).

Head wasn't thinking right in the morning Fixed the chart.

Want to see how this baby performs on the 8800s.

[MagicMANX]

yeah looks interesting, if its a lot cooler, i´ll consider changing my VF900 with that dual orb on the 8800GTX.

very nice graph,thanks a ton for that

you rite




the RD600 is a big problem ,in bad conditions it hits 60C+ easily and part of that heat went to cpu area

[Morais]

Very good review and pics PcCriminal, thanks for sharing

[RubberDuck]

if it's performance that you want, get the Thermaltake

Cool I was looking at that VGA cooler and with your review I'm going to get it.

Thx

[dr4gon]

very nice pics! How's the noise difference between the zalman and Tt as far as you can tell?

Tt works great(it's my opinion) with a low level of noise and don`t need any speed controller,its only 21dBA @ 2500rpm

Zalman you can adjust by yourself the speed
in silent mode -> 18dBA @ 1350rpm
in normal mode-> 25dBA @ 2400rpm

[DoomSayer]

anyone put this on a 8800GTX yet ?

[kite7]

anyone put this on a 8800GTX yet ?

PcCI2iminal did, he didn't post the results yet though so just be patient

[PcCI2iminal]

sorry for the delay.

Asus 8800GTX + Tt DuOrB

I was testing and re-checking all the tests and looking for a possible mistake in the instalation and the contact was perfect ,I have tried several times but in all tests the 8800's core reached 100c.....

here is the numbers
idle 48c load 100c


idle 47c load 104c


How it can be great with X1950 and so bad with 8800...I'm very confused


Thermal paste-> Artic Silver AS5
Room temp->25c

[Sparky]

8800GTX puts out much more heat than the X1950, saturating the duorb? Would be my guess, it just can't handle the heatload.

[Nicksterr]

Wow, that's horrible. Sure it's not an IHS contact problem?

[PhilDoc]

Must be something wrong, you'd think it'd perform better than the stock hsf

[Vapor]

When it's loaded, it may just be too much heat for those two (low cost) heatpipes to handle...idle temps are very, very good.
