M4400 AS5 how to.

Good guide. Your warranty is technically void right now, right? Of course what Dell doesn't know won't hurt them .

I won't try this yet, because I feel my CPU/GPU can fluctuate by over 15-40 degrees at any given time. Being 5 degrees lower might just be the temperature reader being its funny self, but you're right it could be the AS5 working. Gotta run heat tests to find out for sure. My CPU idle is 33.89C and GPU idle is 44.89C @ the moment. I remember often my CPU jumps from 157F to 104F, in a second from finishing a process.

Let me know if the overall system gets cooler over time, I would love to do this for my GPU and possibly overclock even higher and break 8300 on 3DMark06. Is there any better compound than AS5 that can cool a GPU down by 10C? I would pay for that...definitely.

 

There's also some kind of liquid metal available. Search the net for it. If i remember correctly, the maker was Coollaboratories or something.

 

hi..need a bit of clarification: the original dell thermal compound is a paste? not a tape?

just checking cos i remember reading on some vostro models it was loose after removing the tape, and one guy made a copper shim to make up for the gap.

im assuming none of this will be needed for the m4400? just a simple wipe off the old paste, apply the new?

thanks

arnt those liquid metal things dangerous cos they have electrical conductivity as well?

 

Hi guys! Been away for a week but good to see there's a guide for AS% now!! Did it myself right after receiving my replacement system and as far as i can tell now it knocked off around 5-6c for the CPU and around 8-10 for the GPU...VERY happy with that, just what i needed for the GPU actually. I OC'd it to run around 7100 3dmark06 but sometimes the temps could go up to 86c...right on the max for me but now it never goes over 80 (usually around 77)

 

btw...AS5 does conduct electricity, be sure not too put it on any contacts. I don't know how much of a risk this really poses but they warn for it on the website. They say it "could" conduct as there are tiny amounts of silver in there which are conductive.

Btw Ram...where did ur rippleback sig go?? Care if i'd continue on a good idea?
Not too happy with my own in the end

 

Yes its a paste on the GPU and CPU cores,wax pad on chipset and video memory modules.

If its applied correctly,you won't have to worry about conductivity,it pays to clean the old paste off with alcohol before applying new paste......don't remove the blue wax pads for the chipset and memory chips,because like you say,there will be a gap

 

will the fact the pads are removed and then put back in place negatively affect the cooling of the chipset/memory in any way?

 

Not from my experience,just be careful not to touch them or damage them

 

It's still there, I see it! If you want to continue on it go ahead.

 

The newer M4400 have paste. The first M4400 had pads. I changed the pads against paste and it improved temps about 5°C during idle and about 10°C during load! Perhaps the pads are easier to install, but they performe very bad! Dell should get rid of them!
