Or, if you want one of the coolest systems about, how about replacing that nice quiet fan for a <A HREF="http://www.deltaww.com/products/dcfans/pdf/FFB12012038.pdf" target="_new">Delta FFB1212EHE</A> kicking out 190 CFM, and 59 dB-A @ 4000 RPM.

Bloody loud, but 190 CFM is massive air flow.

Campbell...

P.S. I've got an SLK800 - might look into one of those quiet fans, good idea.

WOW THATS A POWERFUL FAN!!! For someone who doesn't care about noise, thats THE ultimate fan!!!

Of course, you could always get some sound deadening material...

Those adapters are not so great. The don't work all that well and the extra distance that they move the fan away from the socket put a lot more stress on the CPU die and the socket itself.

That heatsink weighs 505 grams. That is a lot of weight. AMD's standard is 250g for a single clip heatsink. This is based of the information on page 20 of the <i><b>AMD Thermal, Mechanical, and Chassis Cooling Design Guide</i></b>. However again that is for a single clip. The stated amount of pressure on the die is a max of 16-20lbs. So 500 grams attached to the motherboard and using a spacer would be fine. However the Thermalright SLK-800 attaches to the socket. That is a lot of weight for the socket to take. I <b>recommend</b> that you would remove the heatsink every time you transport/move the case. (LAN parties, move it to work on it, etc.)


Campbell,

I hope that you realize that that fan weighs 370 grams. ???

That with the 120mm-fan adapter will either crack/chip some part or corner of the core; or you will stress it to death. You are talking about...

505 grams + 370 grams + the adapter = over 875 grams. You are probably talking about 16-18+ lbs. of pressure. (only a guess... Find an engineering student or ME to do the stress calculation. <A HREF="http://www.design.alfred.edu/mechanics.html" target="_new">Stress Equations for solid bodies - see axial and perpendicularly loaded bodies</A> or <A HREF="http://www.xs4all.nl/~johanw/physics-hyperref.pdf" target="_new">For a really good set of Physics Formulas go here</A>.)

Add in the vibration of the fans and the initial torque of the fan at startup and you can add some more stress.

All I am saying is that that is getting dangerously close to the limit and I would not want to get anywhere near it.

At least with a screw-down method like the Swiftech or the Alpha there is stress being distributed to the motherboard.

Another thing is that a 120mm fan will not allow full concentration of the air onto the heatsink. If you use the adapter you get restricted airflow. So the total CFM will not be what you get. There will be air resistance as it is channeled from the opening 120mm^2 down to the 80mm^2 exit.

92mm fans using the grill method is best. You will not be using the 120mm dual bladed EHE fans or the triple bladed designs. But let’s be realistic here. Panasonic, Delta, Sanyo-Denki, and Papst all have good 92mm fan. In that order Panaflo to Papst is the best CFM/dBA ratio. They are all about equal but the Panasonic wins in the 92mm category.

Okay… I said way too much here.

If you would like see some more comments on weight, heatsinks, and fans read this thread.

Back to you...

Sorry to burst your bubble Paul...

That fan could suck in some smaller house pets but look at this one. It is <A HREF="http://www.deltaww.com/products/dcfans/pdf/GFB120120762.pdf" target="_new">Delta's triple-bladed GFB1212VHW-F00</A>. Try 220 CFM and 59dBA.

However you would also not want to use this on a heatsink. It weighs 570 grams.

ok, how's this? Will this setup be enough cooling for an AMD XP 2000+?

Also, using <A HREF="http://www.2cooltek.com/retro.html" target="_new">the grill method</A>, is it possible to connect a 120 mm Vantec Stealth Fan to a <A HREF="http://www.thermalright.com/ax7.html" target="_new">Thermalright AX-7</A> with EFFICIENT air flow? - I'm worried that the middle of the AX-7 will receive no air flow because of the fan's motor.

DO YOURSELF A FAVOR, if your really interested in upgrading your hsf...

A little history on my post here first...

I had a Cooler Master HHC-001 HSF w/ an 60mm to 92mm aluminum blue anodized adapter, mounted to this monstrosity was a 92mm sunon 44cfm, 32dba bb fan.

My core temps were anywhere between 46 degees celsius and 55 degrees celsius...Ofcourse I was oc'ing my amd xp2000+ to 2200+ speeds, but I expected the hsf setup to be a lot better performing.

I lapped the heatsink, used ASIII, and everything else that I could think of in terms of preparation...Needless to say I was very dissapointed in the performance, so my quest for a more qualified hsf began.

A couple of days later and a couple of degrees hotter, through all my research, I finally settled on the Alpha Pal 8045, but I did'nt stop there, being that the Alpha Pal takes an 80mm fan and my case also has two 80mm fans, I ordered four <A HREF="http://www.coolerguys.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=001&Product_Code=F-CF808025VRL&Category_Code=F-80" target="_new">crystal clear</A> blue led 80mm fans 52.6 cfm, 43 dba, rheostat adj., they are buy two get one free at <A HREF="http://coolerguys.com" target="_new">http://coolerguys.com</A>

So anyway, I recieved all the aformentioned goodies and installed them. The Alpha Pal 8045 fit perfect on my Soyo Ultra Platinum board. Fans give off a nice warm blue glow too. I have the Cooler Master ATC-210(fog verdant) case.

Now my core temps average 37 degrees celsius and 42 under load...What an improvement, and now I'm running rock solid stable..could'nt do it w/ the HHC-001...

So, Alpha Pal 8045 gets a 9 out of 10 from me...I love the way they cold forged a copper core block into an aluminum base, hats off to Alpha on this one, great job guys...

Wow, that's pretty cool for an oc'd AXP2200+. The thing is, I'd like to have something quiet. Something under 28 dBA. Which is why I'm asking if an 80mm Vantec Stealth and SLK-800 HSF combo will do the trick on an AXP2000+.

Will it? Yes? No? Too weak a fan?

Would it be better to use the grill method with an AX-7 and an 120mm Vantec Stealth? Will air flow be efficient??

By the way, what's the minimum CFM an AXP2000+ needs?

Any input would be much appreciated,

THIS REVIEW IS FOR YOU BUD,

<A HREF="http://www.hardocp.com/article.html?art=MzE3" target="_new">SLK-800</A>

Check it out and let me know what you think.

As for the Vantec Stealth, I think you will do yourself injustice to settle for a fan that only puts out 27cfm. You could do better,stay with an 80mm fan, but pick something with more cfm, for example something in the range of 36dba or so...Go <A HREF="http://www.coolerguys.com/Merchant2/merchant.mv?Screen=CTGY&Store_Code=001&Category_Code=F-80" target="_new">here</A> and look at the 80mm fans, it's where I got my <A HREF="http://www.coolerguys.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=001&Product_Code=F-CF808025VRL&Category_Code=F-80" target="_new">crysal clears</A> w/ adj rheostat rpm (noise) control

I am running the SLK800 with a <A HREF="http://www.thermaltake.com/products/dcfan/a1357.htm" target="_new">Thermaltake SmartFan II</A> - have the temperature sensor under the CPU (the wires are thin enough to fit between the pins) on my XP1900+ running at 12 x 137.5 MHz (1650 MHz)

I runs about 3000 rpm and isn't too loud, quoted figures are 17 dB at 1300 rpm up to 48 dB at 4800 rpm, not sure how linear this graph would be though, probably about 30 - 35 dB for me

This fan is moving about 45 - 50 CFM of air (20.55 CFM at 1300rpm to 75.7 CFM at 4800rpm). Again this is a guess as don't know how linear the air flow is between these two quoted figures.

Temperatures sit about 48C and ambient temperature about 20 - 25C - always under full load as run distributed folding on it. (I have an MSI K7N420 nForce board - have heard the temperature sensor if pretty poor on these, so 48C could be a bollocks temp...)

Hope this gives you an idea of temperature / CFM for a chip pretty similar to your own and with the same heatsink. Oh, using Arctic Silver III, but since I am not that careful, might not be very well applied, too much, etc.

Campbell...

P.S. The 120mm Delta probably is a really bad idea - something spinning that fast with that much weight would cause massive stress to the 6 plasic mounting clips on the socket - only a matter of time before they broke.

P.P.S. I must admit, I spent a long time trying to figure out which heatsink to buy - I was gonna get an Alpha Pal8045, but couldn't find one in stock, then I bought the SLK800 as a couple of reviews rated it slightly better (although some rated it worse too - nothing much to choose between any of these massive heatsinks really).
<P ID="edit"><FONT SIZE=-1><EM>Edited by campbellcopeland on 09/02/02 04:36 PM.</EM></FONT></P>

Hmm, thanks campbell. I think I may get that setup... I really only need it to be quiet overnight while I sleep. If it's loud during the day, it's fine. So my question is, if you leave your computer with no activity, will it stay at or around 17 dBA/1300 RPM?

TIA,

What are the dimensions of the SLK800? It looks big, even bigger than the AX-7. Is it smaller next to the core, meaning does it taper?

<b>I have so many cookies I now have a FAT problem!</b>

The dimensions of the SLK-800 are as follows:

L87 x W56.4 x H48 (mm) - Top, without fan
L57.5 x W56.4 x H48 (mm) - Bottom
L25 x W56.4 - Base

(These specs were taken from the <A HREF="http://www.thermalright.com/slk800.html" target="_new">Thermalright website</A> )

-Paul2200

Under no load, I think my CPU sits about 40C and about 2500 rpm on the fan (not sure about this, it is usually always loaded). Should be under 30 dBA, but not certain about that.

The fan also comes with a rheostat thingy (variable resistor) that allows you to manually reduce the rmp of the fan - might be worth turning it down at night if it's too loud.
