Zalman Cooler Opinions?

I was looking at getting this one: 7000, but it looks like it only works with Pentium4 & Athlon64 and I've only got a measly Athlon XP. Can anyone point me in the direction of a good review site with quite a few Zalman's reviewed or any personal opinions of different fans? I've got a quite PS, but need to quite my processor fan down.

Zalman's do seem to be the preferred cooler for extreme quietness. But they aren't the best coolers.

I got a Thermalright SLK-800 heatsink which is does an amazingly good job on my overclocked Athlon. I added a Thermaltake Smart Case Fan 2 which allows me to adjust the fan speed to compromise between cooling level and noise.

Try these reviews...

Thanks for the links - they're pretty dated, but helped a little bit. The SLK-800 looks great though - I'm not looking to spend too much right now since I'm trying to save up for water cooling...

I got the SLK-800 for $30 from SVC. They have it priced a little higher right now but you could look for a deal.

The fan was about $9-10.

i've only used a Zalman passive unit once (i think a CNPS6000CU), and it was really good. the temps were slightly higher than with a thundering volcano in there, but it was SILENT.

i am thinking seriously about getting the zalman passive heatpipe for geforce4 cards, but i might need a bigger case for better airflow.

Could someone confirm that the Soyo SYKT333 Dragon Ultra motherboard has the four holes for mounting an SLK-800U:

It looks like they do here...but can't quite tell:
http://www.soyousa.com/images/produc...eled/KT333.jpg

Here's another picture I found of the board:
http://www.tech-report.com/reviews/2...a/index.x?pg=2

Thermalright's site doesn't help much:
http://www.thermalright.com/faq_800u_Motherboard.html

Also, could anyone recommend a thermal paste? I have used the Arctic Silver III in the past, but now there's others out there - any thoughs on the Alumina Premium Ceramic Thermal Compound or the Ceramique High-Density Thermal Compound?

(X, you can post that coupon here if you want - it appears to be a generic $5 off - the shipping at SVC, along with the fan being out of stock made me go with another site - they have good combo prices - 800U for $29 & Smart Case Fan 2 for $11 and cheaper shipping via UPS)

I've been reading more and more about how good thermal tape is superior to good pastes. AMD is recommending it for semi-permanent installations and saying only use paste when you know you'll be removing the heatsink soon.

The SVC coupon, good until 6-2 is afa98292ea.

(blake here, but don't want to log gregx off )

X, I installed the heatsink and fan today and had a question about the Thermaltake Smart Case Fan 2. It comes with a temperature sensor - should I sandwich that between the heatsink and processor or does it go somewhere else? Also, is it even necessary if I am plugging the fan into the motherboard - can't it read the info from the sensor on the motherboard?

Thanks!

I didn't use the temp sensor so I didn't check to see where it would go. I'd imagine as close to the core as possible, but on the heatsink might be ok.

I used the rheostat so I could dial in a speed that would be quiet and still provide enough cooling. I run several degrees hotter than the fan is capable of cooling, around 3900 RPM, and mostly tune it "by ear" while watching the RPMs and the temps.

Thanks - I placed the sensor between the heatsink and chip - should work out - right now, been running at 100% for 10 minutes and my CPU is 10 degrees cooler than it was before - 34 Celcius - but I have the fan at full speed - oddly enough, the rheostat doesn't seem to slow the fan down - the fan only steps down when I unplug the rheostat completely...oops - just went up to 35 degrees.

I think next time I restart, I'll unplug the rheostat and see if it auto steps and check the temp and if it doesn't i'll plug the rheostat back in and kill the temp sensor.

Lovin the 800U

You have to put on a jumper or something to make the rheostat work. I'm surprised you don't hate the noise of the fan at 4800 RPM.

I do - it is waaaay too loud - have to find the instructions online I guess - nothing in the box for the fan...would have never guessed to put a jumper on somewhere.

X, do you have instructions? I can't find anything on their website or at review sites as to the jumper...checking soyo now.

It appears you have to look very carefully at the pictures on the back of the box.

I guess you have to remove the jumper. http://www.viperlair.com/reviews/cas...martfan2.shtml

I seem to remember it being a little more complicated than that though. If you can't get it working I'll open up the case and check it out.

Thanks X - the 3rd link Mr. PC Pro had the answer:

Then I shutdown and enables the sensor by removing the jumper and plugging in the sensor instead. When I re booted my system just beeped and shut off. After some troubleshooting I discovered that my BIOS was preventing the system from running to protect the CPU from a low speed fan and possible damage. I disabled that option and rebooted with no more problems. Talk about noticeably quieter, wow. Again I did the same test and here are the results.

That makes sense.

I didn't have that problem. Maybe because I started out with the pot turned all the way up.

Many thanks X - I found the speed of about 3000 RPM to be about the same noise as my "whisper" power supply.

Speeds and temps:

36 @ 4800
38 @ 3750
40-41 @ 3000

Edited...looks like at 100% for a good half hour at 3000 RPM got me up to 45 degrees. Same I was running before, but much quieter. I think I'll ratchet up the fan a bit since I was testing it all with the side panel off and get back down to around 40.

Before this cooler, I was running a constant of 44-46 degrees and much, much louder. So I lose quite a few decibels and drop 5-6 degrees. Not bad and well worth the money.
