renolle Posted February 22, 2006 Posted February 22, 2006 Question 1 I noticed that the tempdiode for measuring pwm is close to the R60 marked black box(whatever that is). My PWMIC temps are in the high 60s when running full and I wonder what kind of mod I can do to help these temps. Since I have a P180 I cant/wont put a fan in the 5.25" area. However, I have some left over zalman heatsinks from my graphics card. Can I put those on the R60 boxes, or doesnt those get warm/unnessesary? Question 2 One ram heatsink on my graphics card has fallen off and I wonder if thats anything to worry about. Theres not alot of air blowing on it as you can see here http://img304.imageshack.us/img304/1387/case2hi.jpg I would like to OC the gc, but I dont know if I can damage the rams if heatsinks are missing. /Olle Share this post Link to post Share on other sites More sharing options...
Mord Posted February 22, 2006 Posted February 22, 2006 NEVER underestimate heat! Especially when you're watercooled. You HAVE to get a 120mm fan blowing directly at the PWMIC and ram modules! The same goes for the video card ram chips. Why wouldn't you put the sink back? DON'T play with water if you don't have enough air moving inside the case! The PWMIC is right there with the R60's.

ripken204 Posted February 22, 2006 Posted February 22, 2006 im trying to figure this out too, i have a p180 and my pwmic area is getting pretty hot, but i'm air cooled. there is just nowhere to mount a fan. they only thing i could think of would be to cut a hole right above that area and put a fan there, but i dont have any of the tools to do that.

PL4YD34D Posted February 22, 2006 Posted February 22, 2006 why not retro fit a hi cfm 120mm fan on the inside of your case side panel. use 4 erasers, some good multi purpose glue and some double sided velcro strip. you can get that from most clothing or dress repair stores. just stick the erasers at the points where the corners of the fan go and attach the velcro ... well you get the idea... that should give adequate cooling and the velcro provides good vibration dampening. you could even put two in above each other to accomodate your gfx card Share this post Link to post Share on other sites More sharing options...
renolle Posted February 23, 2006 Posted February 23, 2006 Well, first of all I have the 2 tri cool fans at the top and back which cools the ram modules good enough, they are never over 30-35C (if I trust my hands anyway). Should I move a tri cool fan from the top and put it in the inlet on medium, and move the Adda 16dB to the top? That would probably be good enough for the GC colling, or? The ambient temp on the GC is idle 29, load 35 right now. As for the R60 boxes I didnt quite get what Mord said. I though the PWMICs are the small chips under the hetsinks, or aim I wrong? Overall the temp inside the case is very good, except for the PWMIC temp, however it doesnt feel warm inside the case even under full load.

HITandRUN Posted February 23, 2006 Posted February 23, 2006 Check out the modification thread! There are plenty of mods for the PWMIC are! I got a mod myself and will post a picture as soon as I make one. It s basically two 80mm fans blowing on the ram! :shake: Share this post Link to post Share on other sites More sharing options...
renolle Posted February 23, 2006 Posted February 23, 2006 I put on some old ram heatsinks on the R60 boxes and tied a 60mm fan from an old socket A cpu block between the atx power cord and the mountings for the cpu block. Im running it at 50% which makes it practically noiseless. Ive been running prime95 for about 10 minutes and the temp hasnt been above 35C! Pretty good with a 50% drop in temps with some old parts laying around http://img139.imageshack.us/my.php?image=10005014vf.jpg Share this post Link to post Share on other sites More sharing options...
espeed Posted February 23, 2006 Posted February 23, 2006 The PWMIC chip is the larger rectangular shaped chip in the corner next to your 24pin connector, just under the vdimm heatsink. Share this post Link to post Share on other sites More sharing options...
renolle Posted February 23, 2006 Posted February 23, 2006 But does that chip generate alot of heat, or is it the chips with standard heatsinks and the R60 boxes? Share this post Link to post Share on other sites More sharing options...
ripken204 Posted February 23, 2006 Posted February 23, 2006 the pwmic thread doesnt help us who have the p180, its a very difficult space with no room, but cools very well(except for the pwmic) Share this post Link to post Share on other sites More sharing options...
case Posted February 23, 2006 Posted February 23, 2006 I stuck a copper heatsinksink on the previously mentioned PWMIC chip and lots a few degrees at full load. I also have a 92mm fan cooling the area at full load with the voltages in my sig im still in the low 50s, whick is ok but I'd love it to be lower Share this post Link to post Share on other sites More sharing options...
