bigger fan = higher temp:(


Recommended Posts

Hi all,

 

I tried a mod for my X2 4400+ stock heatpipe cooler.

Got myself: a Fan adapter to fit a 120mm fan on a 80mm cooler http://shop.freezinghardware.nl/index.asp?...003&ItemID=1847

 

And : a 120mm fan, Papst 4412F/2GLL http://shop.freezinghardware.nl/index.asp?...0003&ItemID=386

The fan does 1600rpm max and 94 m³/h / 55,3 CFM air displacement.

 

Idle the temp is the same as with the original 80mm fan, at full load the temp with the 120mm Pabst(blow into the cooler) is 55celcius instead of 51celcius with the oroginal 80mm fan.

 

Huh? I was expecting to maybe lower the temp by 1 or 2 degrees but I was not so lucky.

 

Maybe time to get an xp120? would that do better with the same fan? Does anyone here have experience with the XP120 and an OCd X2? What's the dual prime full load temp in your case? And what are the specs of your oc?

I recommend the SI-120 as well. Looks like your case is big enough, and it does the job wonderfully, however, if your lookin to see some major differences, I would also invest in a Panoflo 120mm fan. Or one that just pushes out some more CFM. Lots of 80 mm fans can push out 50CFM. Just a thought. Hope this helps:

Yep, also that XP would definitely block some of your ports.

I'd like a Panaflow fan (a bit less noise than the panaflow would be great) but I can't find it here, that's why I got what I percieved as a good second.

bozotheclown.. The reason it didnt help temps is because the stock cooler was not designed to work with such a large fan.. A 120mm fan has a very large dead spot in the middle of the fan from the hub and if the sink isnt made to work with it then you get the results you have,.,

BINGO! The SI-120 is a nice cooler. I have it on my backup rig running a DC opty @1.55v and my load temps are 44c with the Panaflo L1A fan on it on full speed.

crap, I could have concluded that myself, I think you're dead on it (banging my own forehead;) )

 

EDIT OLD I've ordered an si120 and that should do it I guess.

EDIT NEW I've changed my order to a Scythe Ninja

 

thanks for the input people, I feel genuanly stupid right now but that will blow over:)

I just invested in a GIGABYTE water cooling Kit. it was 70 pounds and simple to fit- v quiet and amazingly my CPU temp at full load (SETI Bonic running 24/7) is 36c before this kit it was running at 56c on Full load. All i need to do know is figure how to overclock my system further than 222 FSB !

I got my cpu temp to drop 4degrees by putting LDT and NF4 voltages to default in combination with setting my ram timings to default (3-3-3-8 instead of 2.5-3-2-6) ans the actual speed of the ram (checked in Everest Home 2.20 has not dropped, the latency has dropped a little bit)
