Cooling my CPU

My Thermaltake axial fan just lost control on reboot - I had just finished hacking the case and fitting card board ducting and it was all running sweet
It now wont be controlled by the panel - it just runs flat out (LOUD!!)

Anyone got recommendations on what to replace it with? Quiet is very important, price is a consideration.
It was fitted on a 80 - 60mm adapter. If a 92mm fan on another adapter would be quieter I would go with th that... It just has to be silent...!

 

Well, I plumped for a CoolerMaster Dual Storm DDF-S81 as there wasn't a lot of choice in PCWorld or Maplins.
Super quiet on minimum speed but not cool enough - getting around 56C on barely audible (1800rpm) so I'll mess around with ducting before I speed it up any further...

 

duct tape.....? card board....?

 

Sellotape, cardboard, bits of foam - it's all good
Got it down to 54C with a piece of cardboard and a sheet of thin foam but I think I'm going to have to buy one of those enormous copper heatpipe things to get it any quieter

 

2400+ @ 54c is very hot where does idle top out at? im at 38c with my 3200+

 

92mm papst fan, silent.

 

The CPU idles @ 44C. I was worried about the temp until I realised that the Lowest alarm setting for chip temp is 57C. Remember I've got this running at 2400MHz - SiSoft rates it as a 3500+

 

wtf im at 55 w/ my 3500...how can i get cooler i got 3 case fans and a better heat sink

 

what thermal compound did you use with your new heatsink? and what is the setup of your case fans (location and intake or exhaust)

ideally you want even intake/exhaust, or more exhaust than intake. intake is usually in the front, and exhaust is on the back, side, and/or top.

also, how hot is the room it is in? my CPU temp (also a 3500+, but newcastle with stock cooling) varies as much as 10 degrees C if my room is cold or heated. the Winchester core is noticeably cooler than Newcastle, but 55 isnt bad if it doesnt get much higher than that.

 

i used some thermal take thermal grease but img ettin my arctic silver and my nv silencer 5 in the next couple days which should lower my temp dramatically ive got 1 intake on side...2 out in back and 1 on top that just blows down cus theres no hole at top i just drilled hole to put it there...is taht bad? im planning on drilling holes up there soon but is it bad that it just blows down

 

my cpu right now is at 80! IT GOES UP LIKE THIS SOMETIEMS WHAT CAN I DO

 

right now mines at 138 f and ig ota cooler master hyper 48...id uno whats wrong

 

theres no way your CPU should be getting that hot.

take off your heatsink, make sure you properly installed the retention bracket, re-apply thermal grease after thouroughly cleaning the CPU and the Heatsink with alcohol and a lint-free cloth, and make sure you get the heatsink properly installed.

i would imagine your airflow would be better without the fan blowing down, as that might be swirling the air around (you pretty much want a jet stream of positive pressure blowing air out the back), however if you do cut a hole in the top, an exhaust fan there may help with case temps.

 

fixed it...read my other posts...its chillin at 29...yea chillin...cus its cold

 

The better the separation between HSF intake and outflow, the more effective the ducting is. The idea is to keep the HSF exhaust out of the HSF intake, so that warm air doesn't get re-circulated through the HSF. If the ducting can be arranged so that HSF exhaust gets sucked out of the case by the PSU and/or rear case fan without going anywhere else, so much the better.

The ducting I set up on an AMD XP 2500+ was as effective as a Zalman CNPS6000-Cu cooler -- and a lot lighter and a whole bunch cheaper.
