what cpu fan?

Recently moved to a new house which is a bit hotter than the old one, hence my CPU temp is up a couple of degrees (runs at 48 degrees now). I have a quick question about cpu fans; what would be better to use on an XP 2200, the standard stock AMD fan or a Thermaltake Volcano 6Cu+ ?? I have used the volcano before but it sounded like a plane taking off as it runs at a constant 6500rpm so left it this time.

It was overclocked to 1950 but I decided to put it back to 1800 until I could get the temp down to the 40 degree mark. There are 3 case fans but being in the tropics the room temperature is always over 30 degrees anyway so they dont make much difference. Any thoughts?

I suggest the Volcano fan, loud or not it's one of the best ones I've found for cooling off those overclocked chips.
Perhaps some silver based heat grease (thermal compound)? That always drops the C a few degrees for me...

Why not try putting a Variable Resistor in there with the Thermaltake fan you could bring the speed/noise down a bit as well?!?!

Just so you know, I replaced my Volcano 6Cu for a Volcano 7 because my 2100 had sarted getting high temp readings.

The 7 has never had a heat problem yet and has a switch for different speed settings. Love the full Cu heatsink.

What about just improving the airflow in the case? Adding an intake or another outgoing fan could be sufficient. A blowhole could also be a solution.

Volcano 9 all they way. It is around $30 but it is WELL worth it. My system was running at around 140 - 142 and now it's around 98. If you're overboard on the cooling (below 100 degrees) and it's too loud...turn the speed down. It comes with a fan controller.

Currently using the volcano on my second box (duron) and noticed it blowing air away from the CPU, is this normal?

Also have a Coolermaster HHC-001 heatpipe fan lying around, are they any good? Noticed the retaining clips look very weak, I'd hate to have the thing fall off :flame: and its a big heavy copper heatsink.

The cpu fan should be blowing air down on to the heatsink fins, not sucking it away.

Just an FYI but that is the normal temperature for an XP per AMD.

See data sheet:
http://www.amd.com/us-en/assets/cont...docs/24309.pdf
Page 23 -- the maximum temp is 90 degrees C.


Unless you get reboots or errors, save you money and buy a $5 case fan mounted on the back to make sure the rest of the components in the case stay cool.

I would not go by one word of that document. I called our AMD support line and discusses max temp with them. They said anything over 135 F which is 67 celcius maybe....is unsafe and definately not recommended. I think the 90 degrees is physical breakdown or something hehe. We had problems at 150 farenheight so DO NOT listen to that AMD document. If you doubt what you hear call them hehe.

I have used the volcano 7 and for the price the Aero7+ is way way better its quieter and it has its own speed adjuster which mounts in an unused floppy bay
it now sits in a drawer because I have water cooling by koolance but it was the quietest I ever had

Everybody keeps wittering on about the speed of your fans - errr umm guys big slow fan (which is quieter !) is much better than widdy-diddy fast fan ;)

Its all about the (air) flow man ! :D

Heatsink is soooooooooooo important too, copper beats the sh!t outa those 'alloy' ones.

May be you want to also look at a software to idle your cpu as well which cool your cpu too... http://www.cpuidle.de/

I think the fan with the retail AMD cpu is adequate, if not spectacular, and AMD's current warranty policy states that use of a heatsink and fan other than the stock fan voids the warranty. Likewise the use of thermal greases; even Arctic Silver.

But, if you want to go ahead and change it anyway, I like the Thermalright 800u and 900u series copper heatsinks. They are big, heavy and may require removal of the mainboard to mount. The 800A is identical to the 800u but it has the regular SocketA spring clips. The 900 takes up to a 92mm fan and the 800 takes up to an 80mm. Just like confus-ed says, bigger, slower fans are quieter than smaller, higher speed fans. A Sunon KD1208PTB2 80mm fan moves 39 cfm at 32 db. Compare this to the 60mm Delta AFB0612EH which moves 39 cfm at 46.5 db!

One heatsink/fan I like very much is the Vantec Aeroflow with a 70mm YsTech tip driven fan. It compares pretty favorably to the Thermalrights at around half the price. If you don't want to take a chance on voiding the warranty, consider a higher flow exhaust fan (or fans) for your case. Many of the stock fans are pretty crappy. If you have a generic POS fan, the Sunon mentioned above will most likely be better, and if your noise tolerance is fairly high, you could use a Sunon KD1208PTBX-6A, which flows 50 cfm at 40 db. This approach won't void your warranty, and it also eliminates clearance problems you may run into with some motherboards and the really huge HS/F combos.

Volcano 9. Smartfan II. 75.7 CFM @ 4800 RPM @ 48 dB. Mmm, airflow. The heatsink is crap but the fan muscles a AXP 1700+ @ 2.32 Ghz to 98F idle, 125F load.

My personal recommendation: Set aside $30 or so and get one of these when they hit $20 again and nab a Smartfan II or a good 92 mm fan. Damned near the best aircooling you are going to find for a pretty low cost.

Did you specify Althlon or Althlon XP? I'm not really doubting you but I do know a couple folks who have had XP's running at high temps without issue though I personnaly don't like running chips hot either and go buy a big a$$ heat sink for most of my CPU's and use the Athlon coolers on older systems (works awesome on old k6-s's and pentiums).

Still, if he's not getting issues, then why spend the $$$?
