Arctic Cooling NV Silencer 5 and Zalman VF700 AlCu and Cu Comparison

compared to a stock 6800LE cooler?

*sigh*

the VF700 does look nice, and placed on a baybus can give you idle silence + full load cooling all in one.
but the ramsinks look like cr@p, and arent replaceable due to the low profile of the HSF.

id like to see these units compared to a real GT or Ultra cooler ~ not a 6800LE POS :|
 
The NV Silencer also has the ability to be silent if you use Expertool.

The review doesn't mention how the ramsinks are installed, but if the method requires an adhesive, it marks another reason to get the NV Silencer instead. There's nothing permanent about the NV.

Just look up almost any other review for the VF700 and the AC5 with the 6800gt and you'll see that they are both bettter than the 6800GT stock cooler.

There is an integrated adhesive on the ramsinks. I guess that is a downside the the VF700 since they're probably not very easy to remove and put on another card.
 
there acually is a downside to the NV silencer - they are custom made for a given card series. You can only use it on GF6 cards. The Zalman can be used on all 9x00/X8x0 cards, as well as 5x00/6x00. Since it just uses a standard fastening system, it'll likely work on the upcoming R520/G70 cards, as well, adding life to your investment. Just my $.02.
 
The NV5 can be removed and installed as many times as you want. But, the spacing between the heat sink and the RAM chips is not accurately predictable and may not be exactly the same for all cards. As a result, you may need to fill the gap between the sink and the RAM with extra thermal compound.

The Zalman cooler mounts on the GPU and the RAM chips perfectly. But, the RAM sinks are not easily removable. Also, the cooling of the RAM chips may not be as good as the NV5 because of the small RAM sinks compared to the giant NV5 sink.

This may be an opportunity for the manufacturers to come up with a third design alternative to have the best of the two worlds!

Anyone here wants to start a company and build the next graphics card cooler?

Could you explain this to me? I have an ATI not-so-silent silencer. I know a lot of people here say Silencer's are quiet but I'm afraid that my threshold for what's consider silent is a whole heckuva lot lower. In fact, it's almost universally agreed upon over at silenpcreview.com that the Silencers are FAR from silnet. Quiet? Debatable. Silent? Hell no (guess we're a difference breed). ANY help in this matter would be greatly appreciated!
 
I have a AlCu VF700 on my X850XT running in silent mode and I love it. Cools it very well and I can't hear it at all, and this is coming from a silent computing freak.
 
I have a Cu VF700 on a X700 pro and it runs great on the 5v low setting. Much cooler than stock, and the important part, much much much quieter. My loudest component is my hdd now, and thats even with decent ocing on the card. =]

There is always a trade-off between cooling and noise.
You can decrease the RPM of a fan (different ways) and make it quieter if you can live with decreased cooling performance.
 
Aye. It was suggested that the sound had something to do with PWM noise or something like that? People suggested using a fanmate and hook the silencer up to a mobo fan thingie. I purchased a fanmate and THIS:

http://www.frozencpu.com/cab-32.html. It still doesn't fit though 🙁.


Cooling performance isn't a huge priority as the Silencer at default is giving me a 15-20 degree C window to work with relative to the stock HSF.

I think this is the converter you need.

I take that back!
Can you explain what does not fit?
 
I think the NV Silencer is great, and also, I think that the VF700 is good too. The only reason that I chose the Silencer over the VF700 is because the VF700 can be installed on ATI cards 😛 . No, seriously, the reason I chose the Silencer was because the VF700 was very hard to find, and the whole thing with the RAM sinks, they are relatively small, and if you wanted to upgrade them to be a little more beefy, your SOL. This could hinder overclocking headroom (not like that matters much to me), as well as possibly create more heat, but then again, maybe not. All in all, both are great coolers, and anyone that gets one should be happy with it as it is much better than the stock NV coolers. Though I wished that article had compared the Silencer with the stock GT\Ultra cooler, and not the NU cooler. Oh well, at least my temps are lower with the Silencer.

Well the pins from the fan on teh Silencer doesn't fit either end of the converortor.
The fan seems to have like 3 really small pins that fit on neither the 2 pin or the 3 pin end...

What graphics card, what model? Do you have a link to your exact card?
Most cards have a 2-pin connector for their fan. I am surprised to hear of a card with a non-standard 3-pin fan!
 
No wait. I don't think I explained htat correctly. THe female on the HSF (both the stock hsf and the Arctic Silencer hsf) would fit a 3 pin connector but it's smaller than than the one's found on the standard mobo 3-pin. I'm trying to get my fan to hook up to the motherboard instead of the video card's pin's. I'm using an X800Pro BBA btw.
 
I did not even know that a non-standard 3-pin connector existed!
I have no solution. I will let you know if I find one.

Here is a review where the guy actually tests the RAM temps. One thing to note though, is that they tested it with the case door open.

Very interesting! I wonder how they measured the RAM temperature?
What is missing is NV5 at lower voltage, may be 8V.

I'm assuming they used a temperature probe or something to test the temps.
They probably didn't lower the NV5s voltage since there's no way to do it without modifications or extra hardware.

Considering that there is no sensor on the RAM chips, like there is on the GPU, I would think the best way to compare the RAM cooling between the two coolers would be to overclock the RAM and find the maximum rate in each case.

Otherwise, I would not bet on the accuracy of the measurements if external thermal sensors are used.
 
i bet that the VF-700 Cu cools the ram BETTER then the NV5. Why? because the NV5 uses one copper block that cools the RAM AND the GPU. Al lot of the GPU heat probably gets dispersed to the ram...not very good for the ram.
the Zalman uses seperate ram cooling for each chip, and the fan blows down on the whole card.
