tatts Posted November 4, 2005 Posted November 4, 2005 as anyone got any mods or ideas on cooling the pwmic please? mine gets to around 50-53c when underload running a opteron 146 @ 3ghz and thinks its a little high. also, would it be worth upgrading my arctic freezer64 for a thermalright si-120 & a 120mm panaflo? not sure if the xp120 would fit. it may not reduce cpu temps much but thought it may help cool the pwmic abit? any ideas would be much appreciated :nod: edit: will the Thermalright SLK948U be better for a opteron?

madian225 Posted November 4, 2005 Posted November 4, 2005 Hi I have a seperate 80 mm fan blowing cool air on to my PWM and it works very well, assuming the NF4 Ultra D is the same layout as the NF4 SLI-DR then the chip is located up just above and to the left of the 24 pin ATX power socket on the M/B. Although I am sure if this is wrong someone will correct me Quote Share this post Link to post Share on other sites More sharing options...
tatts Posted November 4, 2005 Posted November 4, 2005 yes its between the cpu & ide connectors but how do you put a extra fan there? Quote Share this post Link to post Share on other sites More sharing options...
lowboy Posted November 4, 2005 Posted November 4, 2005 I put fan above MB, hot glued to MB tray works great! cpu29c-nf4 34c-pwmic 31c Quote Share this post Link to post Share on other sites More sharing options...
hmf Posted November 4, 2005 Posted November 4, 2005 I just installed an artic cooler on my 7800 and my PWMIC temps went from 45+ down to 35 deg at idle. Guess the hot air from the stock fan was hitting the PWMIC senser. CPU temps are down about 4 deg. Chipset temps are down about 4 deg. too. A pleasant side effect in addition to the greatly reduced gpu temps at idle and especially at load. Quote Share this post Link to post Share on other sites More sharing options...
Angry_Games Posted November 4, 2005 Posted November 4, 2005 yep i either use a Coolermaster Crossflow fan (for Stacker cases), or I just put an old 60mm thin fan (ie: the kind from AMD stock heatsinks) in that area with twisty-ties, or hook one hole on the post of my watercooling setup Quote Share this post Link to post Share on other sites More sharing options...
deguello Posted November 4, 2005 Posted November 4, 2005 I just found a unique and easy solution for fan placement. After having done a combination of the other suggestions (I had a small thin 60mm fan twisty tied). I have come up with a solution that so far seems quite solid. First take note that not too far from the row of heatsinks, there are two motherboard anchors with screws holding the motherboard to the tray of your case. I got a bolt long enough to mount a fan to and installed it into one corner of the fan. Then i put a nylon lockwasher and nut over that. I tighten the nut until it just started to touch the fan, but not so tight that I can't turn the screw, yet. Then I insert the long screw, attached to the fan obviously, into the motherboard tray mount hole and turn the screw until it tightens firmly. Then I used a curve pair of needle nose pliers to hold the nut on the inside, nearest the motherboard, and then tighten the screw head itself. If you put the bolt through only the inside hole of the fan (closest to the MB again), you can still put a decorative grill over the fan if you want. I can show you guys some pics if you want. It will have to wait until I get done with my duties today, but this is quite trick and works well. Much cleaner than the old twisty ties and now I have a really good looking AC Ryan blackfire fan with a cool fan grill on display.

tatts Posted November 4, 2005 Posted November 4, 2005 yes some pictures would be nice for ideas would on of these be beeter than my arctic freezer? thermalright SI-120 or SLK948U and which one? (i know AG will say slk948u lol) Quote Share this post Link to post Share on other sites More sharing options...
killermiller Posted November 4, 2005 Posted November 4, 2005 Yes, pics please as I am having a PWM IC cooling problem too. What temps are you getting on your PWM before and after you mount the fan? Quote Share this post Link to post Share on other sites More sharing options...
Gorgias-Flux Posted November 4, 2005 Posted November 4, 2005 Also in line with this thread, I have some issues with my NF4 Chipset getting up to as high as 56C while playing Civ4. The problem I have is that my GFX card basically sits right on top of the poor thing. Any ideas on how to better cool that Chipset?
