well many of you know that i have the Globalwin CAK38 to cool my 1.2GHz Athlon Thunderbird
it is loaded with a Delta fan that bigs 59db
im tired of this loud and annoying fan
it is something hard to live with
larger fans that spin slower yet move the same amount of cfm is probably more quiet
so if i were to buy a special 80mm fan, would a fan duct work well with the CAK38?
I haven't seen a duct with your specific HS, but they can work well. The other option I guess would be a temp activated fan, but if you're overclocking it would just be on all the time, and even if not, AMDs run kinda hot so theres a good chance it would be onn all the time anyway. I'd say if you have room in your box for a duct, go for it. The only thing is, be careful what kind you get. There's a good article here (http://www.maximum3d.com/reviews/fanadapter1.htm) about the problems you can get with adapters. If you make your own, or find one without edges, it should work great, and still be quieter.

The utmost hs is the SLK800 by Thermalright. This hs will accept 50-60-80mm fans. This thing weighs about 2lbs, solid copper nothing else. Extremely large, not quite as large as a Volcano 9. I will recommend this has and use a 80mm fan that blows over 60cfm. There are several 80mm fans that fit this situation, some are variable speed some are constant speed, the variable speed are super quite except if the heat gets up there. I don't see any heat getting very high with this hs. The one I have keeps the MP1800 running at 10.5x166 at 30c idle and 37c full load. I have seen 41c after installing a large suite of software, but gaming for a few hours the cpu is 37c as high as I have seen. I am not bragging on my system etc. I just would like someone that needs a new hs/fan to go this route. The hs is quite expensive, and that keeps a lot of people from buying it. Believe me it is worth every penny.

that is something im trying to avoid
spending 50 more dollars is not what i have in mind
i already have a heatsink
just need a new fan and a duct that works well...
Ok, Just an attempt to help. If you want to use your present hs, I'm sure you will find a way to place a 80mm fan on top of it. I believe they make adapters for just what you want to do.

yes they do
its expensive though
more than 5 USD just for a piece of black plastic adapter...

You can also do a stack design of 2 80mm fans, I have found the stack design ads little sound unless you stack 3 and then there seems to be some kind o harmonic resonance. In the stack 2 design you will get around a 20-30% increase in total cfm. You can also stack dual slower 60's and get decent cfm. Just a thought :)

but both has to be moving the same speed right?
or the lifetime of the bearings will be lowered?

not really, if you get the same fans should be no prob. the internal or first closest to the sink will always run faster for the air is already accelerated byt the #1, the secondary then spins slightly faster speeding upt he air, then the pulling process helps speed the first one up also :) Pretty cool how they work together.

oh
i need some diagrams to work with
but i think one fan is enuf for me
dont want it to be too heavy either

yeah, well two normal size 80mm fans like the sunon units are not heave at all :)
eviltechie
10-08-2002, 12:34 AM
i know but it does add extra weight
i have 3 new sunon fans but i dont want to use them for CPU
i want a variable one with temp sensor
so suggestions please
what about making your own duct without the lip overhang that adds to problems... I know a guy who made one out of duct tape and a cereal box. Sounds ghetto, but it worked, and if you already have an 80mm fan to try with, might as well give it a shot!

maybe but i dont think ill be able to make one that is stable enough that it wont vibrate

You can get these variable fans and shrouds at
www.frozencpu.com
www.crazycpu.com
Both specialize in these types and all other mods.

if i have to spend more than 10 USD
which probably it will come out to be...
i need a suggestion for a cheap yet effective cooler
how much is the SLK800?
perhaps i need a new CPU to replace my cracked and slightly overheating one
but cant afford one now so i can only dream...
i really need something effective, cheap and quiet...

You asked how much the SLK800 is, I hate to tell you they are between $35.00-$50.00 depends on where you purchase from. Then you must purchase the fan, the hs does not come from Thermalright with a fan attached. Some venders are putting together packages with a variable speed 80mm fan or a quite fan that is constant speed. You just need to check with the coolerguys.

Sure, I know you don't need more options but here are a few.
First off, this may be more expensive, but look at this site from Quiet PC : http://www.quietpc.com/
Other option would be to build your own using a cut out soda can... This one is hard to explain but I'll try and find the link. I saw a mod the other day were this guy cut the top and bottom out of a soda can and used x-tra long screws fromt he hardware store to attach his fan to the heatsink. He used this to funnel the air directly out of his side panel thru the window.
________(-----)<-fan_______ side panel
!{ }!
!{ }!
!{ }!
!{ }!
________[ ]________ Motherboard
{} = sides of soda can
! = screw running lenght of can
[] = heat sink.
And for my final little tip, have you tried the 7-volt trick? I have never tried this, but I've heard it does reduce the sound on your fans. So this is at your own risk. The linky is here : http://www.cpemma.fsnet.co.uk/7volt.html
Hope this helps...

Damn... the pic is a little off, just move the tube till it matches up, it's supposed to look like a sidways "H"...
Here's the link to something similar: http://forums.bit-tech.net/showthread.php?s=&threadid=15044&perpage=20&pagenumber=1
Look at the virus tube, in the pics, there are a few better views on the second page.

ive done a mod before adding a pipe from my hsf to my case fan which blows the same direction as hsf
ive found it about the same loudness...
im not very keen on doing the 7 volt mod for my delta fan either...

The Cyberguys have a black plastic shroud, looks just like the aluminum one except it is black and plastic. This one is $12.95 or somewhere therabouts. This would save a few $$. The variable speed 80mm fan will cost about $6.00, that would make your investment somewhere in the $20.00 area if you purchased both items from the same vender. But you would be able to use the hs you have, it probably needs removing and cleaning of the core as well as the hs.

You are not gonna believe the price of this hs/fan. Since you use this, I thought you might need a pocket full more of them. At this price you could buy yourself a few. Might be worth the looksee.

thanx boby
but the FOP38 uses the same delta fan too...
too loud for me and i want copper...
BobyJo
10-12-2002, 08:52 AM
I understand, but $5.00 for the hs/fan, that is almost giving them away. Guess no-one wants this item any longer. At least this would be a great buy for someone that really needs a better cooler than what they have.

10-12-2002, 03:10 PM
yeah
its good for CPUs around 1 GHz range
my athlon 1.2 is special
its hotter than normal 1.2 because it is cracked
so it runs at the temp of a 1.4 or 1.6 but has the speed of 1.2...
maybe i need a new cpu...
