HOW TO: Change the chipset heatsink on M57xRU

If your M57xRU is having some problems of heat on the right side of the palmrest, the chipset is the principal guilty.

​

So what we can do about it?

The stock cooler uses some kind of thermal sponge, the same used on the RAMs GPU heatsink. Thats far from good, compared with thermal paste with a minimal gap.

​

The heatsink it´s made of aluminium, and the retention sistem are 2 points fixed on the board.

​

So there isn´t any regulation system, like springs or something, just a fixed place. To reduce the gap between the heatsink and the chipset core, we need some kind of mod here.

I recomend to not mod the stock cooler, you may need him intact in a future case of RMA. So the best choise is searching the market for a better one(copper) with the desired size.

The sizes should be within 4.5cms by 4.5cms, with +/- 1.5/1cms height. I´ve found an Enzontech CNB-R1 all forged copper. It haves the 4.5cms size but it will need some mod to reduce it´s height to 1.2cms to fit in the M57xRU chassis.

​

Very good laping job here:

​

Because the material is copper and is highly thermal conductive, the best way to cut it is manually. After that to be on the safe side, is better to put some isolation tape on the sides to avoid possible contact with the surrounding components.

​

Finally because of the stock fixed retention system, I´ve made a custom wire clip to simulate de spring effect.

Some AS5 and it´s good to go...

Final work:



​

 

nice work! Could you also report changes in temperature please?

also, why not use this one, which you showed earlier?


but very nice work indeed

 

Great

Great

Great

+ Rep

 

So far the palmrest is cooler now...

Because of the proximity of the chipset to the CPU in the PCB, it´s normal that the CPU temperature be affected. Of course the diferences will not be abismal, but will make some diference in high load situations. The GPU can be affected too.

I didn´t used the SNB-SL1 because of it´s to small size(3.5cms) and to short support holes.

Now I´m giving some time to AS5 cooking(200hours) and then I will post some conclusions.

 

ill await temps from you then start looking for one..

 

I will also be looking forward to those temperatures, although I will probably not go for the mod myself hehe. Still have loads of warranty time. - Although it would be great just to send in such a modded system for repair hehe, I bet the reseller guys would be quite stunned. ^^

Ill +rep you as soon as I can again hehe

Edit: Where did you clip the custom wire clip onto? I see from the enzotech pic that theres small hooks on the desktop mobo for the clip, but are those on the M57RU mobo as well?

 

That`s a pretty cool mod, I love it when you guys do this.
Now we just need somebody to mod the fans or replace them totally and we`ll have the perfect RU ...

 

hey can you tell me what the oem sink was measurement wise from hole to hole and height wise?? i have one in mind but not sure if it will fit. i want to re use the mount points and not the wire as you did. thanks

 

Do I understand correctly, if you use the mount points, you would have to use a thermal pad instead of AS5 because there is too much of a gap?

 

I had reported the same palm rest heat problem since day 1 i received my 5793, how come everyone kept me that it was from HDD?
ps. Audigy your hand looked just like mine.

 

Nirvana , that is the place where the hdd too,but Audigy made thing seem less hot by this mod, apparently.
I know the hdd also bothers me, since when getting up to 55-57C you can clearly feel it.

 

As you can see the HDD is situated on the center of the palmrest, below the touchpad and 1,5cms off to the right. But the heat is located mainly on the right side and not on the center(here the HDD is located). That sugests that the chipset is the culprit one, since the RAM modules don´t heat much.



So far the only heat that I have is some on the center zone, caused by the HDD. The right side of the palmrest and keyboard is completely cool.

About the wire clip mount, I´ve made one from steel wire because of the specific size and situation of the retention holes.

Then I´ve made 2 metal pieces that will be screw to the retention holes and will "grab" the wire clip.

Like this:

 

It´s 4.2cms by 4.2cms with an hole to hole distance of 7cms.

The height is 1.1cms, but you can go as far as 1.4cms +/-.

With the stock heatsink yes, about 2mm gap. With a modded one, depends on it´s retention system.

But for the best contact possible with the chipset is better to use an wire clip than a fixed point.

The wire clip will simulate a constant spring effect, so that the base of the heatsink should contact as best as possible with the chipset core.

 

hmmm this is unlikely, but if there a power supply (12v DC 0.06amps) anywhere near that heatsink on the motherboard?

 

The M570RU-U owners have one free fan slot(12V 1A) so if they want to use a fan there, they just need to plug the fan there.

The M570RU older chassis owners need to do some wire mod, and steel some power from the GPU or CPU fan.

I´ve the adapter and the fan here, but a mod like that should be to extreme for now. I think that just a passive system is enough:

 

that fan was exactly what I was thinking of hehe!

That means something like this might be possible for someone whos really up for a challenge:

 

Audigy, the green area is where i feel the heat from

 

ill tell you when i swapped the hdd out that exact area was the one spot that changed temps.. and when there was heavy use of the hdd that area changed temps accordingly..but i guess the nb *could* affect it some but even after use the nb heatsink on my system was not even really warm to the touch.. i left the lid held on with only one screw on the bottom last night and ran it hard and then immediately flipped it over and the sink was barely even warm at all..

that last sink looks awesome i wonder if it will fit?

 

Its got hole distance 59mm which is too small I think. But then you could cut off those screw holes and fit it with a custom wire clip like Audigy did. Height of that heatsink plus fan is 2cm I think.. might be close there, dunno how high it will go.
But if the fan ends up being stuck at the bottom of the notebook I guess you could still custom - cut an extra vent into your chassis. lol ^^

anyways, heres the stats on that low profile small NB fan heatsink:

SLF - 1
- Hole to hole distance 54.6mm and 59m
- Dimension 37x37x13.5(H) mm
- Fan Dimension 35x35x6 mm

 

I found better one with fan then the one from enzotech:

- only 1.2cm high

Think this one would fit? its also "virtually silent".

 

^^^ that one doesnt have very much heatsink to it imo... i doubt that would be much better than stock even with the fan.

 

It will be +/- like this:



The DDR2 modules doesn´t heat much(If you have Micron D9 chips). So the heat will come principaly from the chipset and the HDD. The CPU will be off the hock here, because it´s one the oposite side.

So the chipset will release more heat than the HDD, but because of the dimensions of an 2.5" hard drive and the direct contact with the chassis, it will be perceptive that the HDD heats more...

 

Thats because of the limited heat conductivity of an thermal sponge VS thermal paste... believe me, that heatsink with some AS5 in it and a proper base <-> core contact would become really hot...

If the heat can not pass to the heatsink, the chipset core temperature will rise because the heat is become acumulated in it and not being dissipated in the heatsink.

Thats the problem here... the fixed retention system that Clevo have used, leave a huge gap between the core and the base of the heatsink.

To improve that point, I used a custom made wire clip to simulate an contant pressure, like an spring.

The copper heatsink was a bonus, and leaved the stock aluminium one intact(maybe I will need it if I have to do an RMA in the future).

 

I think that passive cooling is the best option here...

With a good copper heatsink and some AS5, an Active cooling solution will not be much better.

This one is the best passive sistem without heatpipes on the market... but 3cms height would require a lot of mod work.

 

Old post again . I´m thinking also to mod my nb, but still havn´t found a perfect way........

 

Yah, that is an old thread - but thanks for reviving it - I managed to miss this thread the first time 'round, so I'm glad your post brought it up to the top.

On the substance of the thread - Wow! This really is good stuff, and clearly demonstrates the genius of many of the Clevo owners around here.

I wonder if any of the gadgets and gizmos the various posters found would be of use on the 8660?

 

Just up the thread again, want to mod the M86 Heatsink, does anyone have a good idea?

 

It doesn't need the mod, but you can always replace the thermal pad with a 1mm copper shim.
