R3E IOH temperature promblems

post #1 of 14
Thread Starter 
Hi, long time reader, first time poster.

I recently finalized my new rig and it's up and running.

My problem concerns the NB temps on my R3E, which were idling around ~80 degrees. Obviously a problem so i did some googling on it and found alot of pictures of the POS paste they use for the NB and SB chips.

I found a thread on here where people found a quick fix by replacing the paste with one of there favorites, mine being Arctic silver 5. I decided to do the same and am now seeing idle temperatures of around 65-70 degrees, which is quite the improvment but still seems way to high. Even under load, they are pushing 80 degrees and asus probe pops up and annoys me.

Now the first time I took of the heatsinks I noticed the NB sink took 3 screws, yet only 2 were installed factory. I figured that there just wasn't enough pressure between the chip and the heatsink, But I have been wrong before.

So is that 1 missing screw enough to cause idle/load temps to reach that high? I also considered taking one screw from the SB sink and putting it on the NB since it uses four.

As you can tell i'm impatient and don't want to resort to RMA, with the 6 series issue and all.

Any input would be greatly appriciated

I did not have the Extreme, but the Formula and it was my opinion that the heatsinks are undersized for an X58 chipset, on either hte IOH or the ICH.

They definitely need active cooling, which on the Formula was a problem with a large Video card and CPU after market heatsink like the Prolimatech Megahalem.

Sidepanel fans can work although on the HAF932 it looks like it might be a little to low to help cool the IOH. Increase case flow however you can or replace the sidepanel with a higher pressure fan if possible. It wont be the total answer but should help a bit.

If you have a third screw around try it out.. just be careful you do not over tighten it.

Thanks for the reply.

I understand that the heatsink is small, but i have noticed people with properly assembled boards have been reporting 55 degrees idle temps, which seems appropriate for stock.

I think i'm just curious if there is something I may be doing wrong, because at this point overclocking is out of the question until i drop those temps

Having replaced the POS "thermal paste" (apparently it's actually paraffin wax ) twice, on two different R3Es to install a waterblock (pain to get that crap off isn't it?), to my knowledge all three of those screws should be there. Maybe if you call them they could send you one?

Also, if you haven't done so, install the extra active cooled heatsink that comes with the mobo (small heatsink with a little fan on the side), I hear it helps loads.

Oh yeah I forgot about that.. with a H70 installed you should have room for it

Seems like that is just a problem with all asus boards the thermal compound they use is garbage since you've already got that squared away see if you can find a screw or steal one from your sb like you said but you need to make sure you have good contact on both, one way i fixed my asus was i got an old cpu fan alittle bigger than my nb heat sink and mounted it right on top and i had dramatic temp changes. I know the rampage idles alittle higher than the crosshair normally but my old idle was around 46 after the thermal change and the fan i keep an idle temp between 33 and 35, also i tightened the F*%k out of the screws but not enough to do any damage :-)

Hey,

Yea i already installed the option fan/sink prior to booting. so i have no idea what my temps would have been before the swap.\\

I think i'm going to go ahead and borrow a screw from the SB sink beacause it seems to be doing just fine, hopefully it works.

and if that dosn't work i don't think i have any other options (unless there is another).

Thanks for all your speedy replies!

Edit: yeah the earwax took everything and it's mother to get off, if i ever get ahold of asus, who told me would call me back three days ago, ill ask for another screw.

I wouldn't remove a screw from the ICH, I ran into overheating issue when OCing on the R3F and would get corrupted BIOS messages as a result. (from the ICH)

Alright, report back with temps!

And I understand your pain man. I spent 2 hours with alcohol, q tips, and a hair dryer and I couldn't get it off. Ended up taking an x-acto knife to it.

Original R2E went up to 100+ degrees. The temp at 80 is actually normal according to asus. Even though one missing screw can effect temperatures, your temperatures are nothing to worry about with good case cooling.
