I'm currently running an XP1700, with a Copper Thermalright SK6 HS, and a Delta 60mm (loud!!) fan.

I can't seem to find anywhere that sells silent 60mm fans, so would it be best to buy something like a Zalman fanmate, and just lower the voltage supplied to the Delta?

I also have a Ys-tech 60mm, but that supplies quite a bit less cooling, but for only a little less noise..

Thanks for any help

Vantec makes a stealth 60mm fan that is not too bad. I'm not sure it will have enough CFM for you though.

There is also a Panaflo, which I assume would be better. ( I am biased)

They are both rated at 12CFM, and according to AMD specs, you need 15cfm, but I would imagine that is based on their "standard" cooler. Maybe with the very efficient copper sink, you can get away with 12CFM.

That sink doesn't look like it can take a 80-60mm fan adapter, otherwise you could use a 80mm Panaflo.

I'm currently running my SK6 HS, with a 35cfm Ystech, and the load temps are touching 50C.

I'm not sure it could take any less cooling

My Dad has a Zalman fanmate arriving tommorow, so I might try that and see how low I can go with the cpu fan

Bummer, unfortunately, less DB(a) usually = less CFM.

They the Zalman CNPS6000Cu. Good cooling, no sound.

I'm upgrading in a couple of weeks, and I'm probably going to go for a P4 setup, probably a P4 2.26B.

Should be able to get an Alpha PAL8942 Heatsink, along with a silent 80mm fan.

Plus a new Coolermaster 110 case with 4 silent 12db fans should help

Just a quick note: Probably don't need anything more than the stock HS and a small mod to use an 80mm fan.

Did a mod yesterday to a new P4-2.26B (533 bus) setup. Used the stock HS, ripped out the fan from the plastic top portion, then used it to secure the HS down. Then a Zalman fan bracket was used to position a Panaflo 80L over it.


On the Asus mobo BIOS used, a fan control utility allows the CPU fan to run at 10/15 of the standard 12V (which is 8V), with fan speed regulated according to the CPU temp. Works like a charm. With only one Panaflo case fan @5-6V in the front bottom, ambient at ~28C, the idle CPU temp was ~44C. After 10 cycles of 100% stress in SiSoft Sandra (~10 mins?), temp hit 55C. Perfectly safe, and very quiet in this pretty Lian Li case.

Very similar to the mod used in the P4 silencing article -- scroll to the middle of this page... www.silentpcreview.com/modules.php?op=m ... =14&page=5[/url]

IMHO 60mm fans are too small to quietly cool the hotter modern processors, however you can try the vantec stealth w/ sk6 and try a undervolt of ~0.2v and see if you can get acceptable temps with that. If you can't you really need to upgrade to bigger heatsinks with 80mm fans (at least, bigger if possible).

I just put a Vantec Stealth 60mm on my SK-6 + XP 1500+. Works great - the temperatures are not much different than when I had my 40 cfm YS-Tech undervolted to 5V and it's much quieter.

If u want to keep the delta power u could try and decouple the fan from the heatsink so that the vibrations from the fan won't be transferred to the heatsink overclockers http://www.overclockers.com/tips457/ managed to do this using a small dab of silicon, a couple of spacers and some pencils for spacing it could be worth a try

This is a mod I've tried to use to quiet a Duron 1.3. With a Barracuda 4, I now only hear air turbulence. It's a simple, simple mod to attach a 80mm fan to the SK6: http://www.overclockers.com/tips942/

This guy was in a similar situation until he found this: http://www.gibtek.co.uk/hardware/thermaltakefan.html

Strange. The XP-1700 is hot, but not that hot. I cool my own XP-1700 with a Swiftech MCXC370 together with a puny 60mm-3000rpm-18CFM fan. In my Antec SX830 case with 5 x Panaflo case-fans at 7V, it translates into a CPU-temp of 42C idle (the heatsink copperslab is varm, but not at all hot). Motherboard-temp: 28C and room-temp: 20C.

Everyone discussing CPU temps should remember that temp accuracy and consistency in mobo-embedded tools is a joke. The single BEST test is whether your system is stable under high load -- if it never freezes, crashes or reboots under high load, that's all that matters, isn't it? Trying to compare temps of his system vs yours is really just a matter of yik-yak, fun & curious but not conclusive in the least unless you have absolutely identical conditions & setup. Raider's setup could be reading the diode, for example, while Ralf63's is working off the in-socket thermistor, and both could be reporting high or low. We also don't know anything about the ambient temps & other gear in these computers, so...

Correct - therefore I always take into account how hot the heatsink-base actually feels like if I place my finger on it. And the copperslab is quite varm but not directly hot, and the system is stable. This translates into around 45C in my book regardless what the thermistor reports.

I think depending on the cpu and clock speed they have different operational tolerances. For example my duron 750 clocked at 800mhz is perfectly stable at the in socket reading of 65c, wheras once I overclock to, say 1ghz, it will crash at around the 55c mark or so. I also "calibrate" my fingers to temperatures once in a while and I find that when my in socket thermistor reads over 45c I cannot keep my fingers on the copper base of my swiftech without it being painfully hot, wheras 40c is quite comfortable. I suppose in socket thermistors is not the best way to compare, but it is MY best way, and I did bend it up to touch the bottom of my cpu and even put a dab of as3 on the tip of the bulb;). KG7 mobo with the extra long probe=). Whew I got really unorganized near the end but hopefully there is a point to this post in there somewhere...
