p5wd2-e premium temp/stock cooling fan issues?!

post #1 of 6
Thread Starter 
anyone used a stocky on these? I have a pd 940

I know stocky's suck, although admittedtly at least this time intel used copper in the middle.

I have watercooling, just need a new part to get it working which will be today/tomorrow. So just a TEMP solution, lol...

Anyway, it would appear that the (cant think of word for little things that stick out around your cpu to give it power..transistor?) are touching the bottom of the heatsink, and causing CRAZY CPU temps, I've seen it go ~ 84 when loading, im scared to do anything other than post here to try and find the problem, they sit around 60c and im gunna temporarily underclock my system.

Could the environment stuff around with the reading, ???

on a side note: I did once stuff up when I had watercooling - I forgot to connect the power for the w/c'ing and turned the PC on, the PC shut down due to overheated CPU. However, when connected all back up it went back to it's normal temps. So I dont think that's the problem?

Any insight..anyone else used a similar setup with scf ?

The stock heatsink should not touch anything. Check the mountings to be sure it's on right and redo the thermal paste and test it again.

My 920 on the Premium ran at 72 load with the stock HSF (stock settings). I don't think it was touching any other parts, heck, I was doubtful it was even fully connected (but it didn't move and when I pushed on it slightly it didn't jiggle and the board moved with it)

The layout on your E-Premium is probably slightly different, so it could be hitting something, but I would not run my system with the stock HSF. These dual cores, 65nm or not, seem to run a little warm. Even with my side panel off, a Zalman 9500, and AS5 it loads at 55c and idles at about 45-46 with a 22-25c ambient. (OC'd to 4.01, 1.3v).

I think the trouble is that Intel used large, thick single fins at the base and then radiated out to thinner fins on the outside. I think lots of thinner fins would have done better, but........

thanks for the reponses guys,

the fan clips in all fine, all four bolts click in as they should, so i cant tell which one isnt in right. I've installed plenty of these and never had an issue,

i will be changing it with the big water copperblock, so that wont be an issue when that's in

I think they mighta designed this board thinking that no one would possibly run a stock HSF on this motherboard (as i doubt anyone actually would) except in my case as a temporary..

anyway maybe ill bring this to light and other people could mention it if it happens, could be an engineering error, however if it was it would be a HUGE one.

ps: tested and wont load over 60c when pressed lightly, but goes 88c+ once released, it will still work at 95c which is kinda amazing, dont feel very good running at that as it will shut down (only a few seconds)

thanks guys!

One question I did have about that was --

Can I use a backplate from (for example) a Zalman 7700, the 775 backplate and install the Thermaltake T plate on the back of that, to replace the washer and mylar (insulating pad) on the back of the motherboard which came with the bigwater kit? (ive swapped mobo's and cant get it off the other one, so im looking for alternatives....am open to idea's!)

I dunno, I don't think it's an issue with the board. In fact, the board is specifically designed to run cool. I think the enginerring flaw lies with Intel in the design of the heatsink/fan attachment. As you found out, when you press on the assembly it cools better (I got the same results just not as extreme, only changed temps by about 6-8 degreees)........which basically tells us that the assembly is NOT being kept tight enough with the lame plastic press in clip design of the stock HSF. If you think about the design of the 478 HSF, with lever's to maintain tight pressure, and then this 775 system with just press in clips........I dunno what they were thinking. Maybe they work ok for single core CPUs ok........


Not sure about using the different backplates as I am not familiar with the Thermaltake set-up.......

the backplate would do an identical thing to what thermaltake gave me..

It was an insulation pad, about 5mm thick which stuck directly to the underside of the CPU, going over the solders underneath to 'shield' them...

the plate that comes with this fan sticks out about 7mm (give or take) so it's bigger (which is fine, because the screws i have are about 1cm too long anyway...

the ONLY concern i would have about using the backplate from zalman would be that it wouldnt cover the entire underside T plate leaving some of it exposed, hovering approx 6-7mm over the back of the motherbord. As far as I can tell it's made of aluminium. So the plate wouldnt be near to touching the motherboard which would seem my only concern.

any help please...trying to get my PC up and running ASAP without all the mess around to reinstall my watercooling block,

a name of a replacement material even??

thanks!! it's ALMOST ready to begin the OC, this thing is a beast except for the RAM (next upgrade)
