Doing a rebuild into a new case and thought it was time i did the cooper cooler bolt mod for my mobo.

Got the heatpipe assembly off. It was only touching half of the southbridge, north bridge seemed fine except they use a thermal pad.

The pwm were terrible. Only 6 of the 12 made any impression at all into the thermal pad and two of those were really faint.

It was no wonder when overclocking to 3.8Ghz I hit 105C on the pwm :eek:

Anyway, all set to put back together but I can't find any 1/2" or 3/4" bolts small enough to fit the heatsinks and mobo.

ANybody help Please?

If it's a competitor to ocuk then please email in trust.

Cheers.
 
What is the hole diameter?

I would think M4/25mm set screws would do the trick.

Something like THESE

I would measure them first to make sure, by the way on my Abit IP35 my NB heatsink is at an angle also ( not seated flat), very poor design by Abit!

My temps while stressing with P95 go way over 120deg but i believe they are rated upto 200deg anyway.

Thanks for that answer but they are much smaller. I bought some M4's last night on my way expecting them to be the same hole size as the cpu mounts but they are much smaller :(

They are the same size as satandard holes inthe side of hard drives etc ( I checked by using a hard drive screw to make sure it went through the holes.

By my reckoning, I need no bigger than 2mm. Help!

I know a lot of people on here have done the bolt mod to this board and I would like to do it before putting it back in.

As for temps my alarm went off when it went to 105c plus I noticed the default for the pc shutting down is a temp of 110C be default. Although it might be safe hotter, I just think thatis too hot for my liking.

Plus people with the bolt mod report temps dropping by 20C plus which can't be a bad thing in my books
 
You need M3 bolts and nuts. Should be able to get them for a few pence each from any decent hardware shop (I think I paid 5p for each bolt and 2p for each nut).

It's certainly worth doing it.

Cheers. Job done now. All put back together in my new silverstone tj09 case :D

Temps much better and heatsinks now warm on the mobo.

Very pleased.

With new psu and this bolt mod, now back up to 3.8Ghz stable overclocked. It seemed my cpu waterblock benefited from refitting as cpu temps now 5C less under load.
 
Primed for one hour last night and cpu hit 62C and pwm hit 68C which I am well chuffed about.

The superb airflow cooling in the tj-09 case might be helping keeping the mobo heatsinks cooler now but the heat has to get to the heatsinks in the first place!

I also notice the temps have dropped on my w/c 4870 now. The core is the same but the memory and card temps are both down a few degrees.

I actually spent two hours routing the cables in this case whereas my old case looked like I had just thrown them all in!

Gary, well worth the less than £1 cost in bolt modding this board. I used ceramique.

The only reason I didn't do it when new was I wanted to try the board first for a few weeks to make sure it all worked right and I had major c1 boot error problems for ages until I got that all fixed.

Also notice with my new psu, that my c1 boot problem which had raised its ugly head again has gone away. Trying to overclock past 3Ghz with saved bios prime95 stable settings just kept producing C1 errors all the time.

Guess my Tagan 480W really just wasn't up to the job.

Another added bonus and not sure whether the cooler gfx card or better power supply is the cause is that I managed to run 3dmark06, vantage and crysis benchmarks at 890/1100 last night whereas the best I could manage before was 875/1090 on vantage and only 839/1090 on 3dmark06 and crysis.

Overall I am one happy bunny :D
 
Shall be doing this mod on my mobo next week hopefully as, my PWM temps are stopping me hitting 3.6GHz, although my idle temps for the PWm are 43c, but when i touch either the north or south they arent even hot, just barely warm, so the contact must be rubbish, so need to reseat and bolt mod the heatpipe, is Arctic Silver 5 ok to use?

Will these be ok for the mod:

Or are they not long enough?, what about them being metal, should i get some plstic washer to do between the bolt head and mobo??
 
Not long enough. You'll need atleast 25mm long. And yeah you'll need nylon washers to place between the bolt and the motherboard.

Arctic Silver 5 will be fine for the north and south bridges. The PWM's have a thermal pad that can be re-used (tho I removed it and used MX-2 on the PWMs. It's unconductive, unlike AS5).
 
What are you using to check the temp of the PWM.

After 15mins of running P95 mines at 52c via everest.

So at that temp Im guessing I dont need to do the bolt mod.
 
Yeah im using Everest to check my temps. just stress testing @ 3.4GHZ atm and the PWN reading is 75c with 1.340 Vcore according to CPU-Z, have tried for 3.6GHZ but i have to have the voltages a lot higher 1.5+!!! and the PWM1 temps get to about 100-105c!!!
