M860TU Cu / Backplate Mod

All mods finished, with total fast 40 copper blocks and some vents on the backplate.
Still waiting for the sekisui to replace the original thermal tape.

 

nice pics. looking forward to your results kaltmond. where did you get that heat sink for your hdd?

 

Looks like a SSD.

 

Yes, it`s SSD X25 , not heat sink......

 

oooooo. i just saw it in your sig -_-. silly me. haha.

edit: i noticed hyou made mods to your fan. did you notice any differences before you added the blocks?

 

wow..lots of copper..cant wait to see the results

 

how do you make the cooper stick together?

 

Ideally, Sekisui 5760 thermal tape.

 

That copper heatsink is sticky by default. Have the same. But put only 8 of them (4 middle cpu, 4 on gpu), instead of 32 =)

P.s. Hmm, where is SovSun and his "huh, another SN for my collection!"

 

I think he just used the tape that came with the blocks. Thermal transfer is noticably diminished if the blocks aren't thoroughly lapped and paired with Sekisui #5760.

kaltmond. What did you do with your last eight blocks? There is still plenty of space on the GPU.

I already have his serial number from last time. It's like Pokemon. I gotta catch 'em all.

 

The GPU actually cant take any more. If they are placed at the copper rod that connects to fan for example, the case cannot close. (Same thing to the metal part)

 

I wasn't talking about the heatpipe or the bracket that anchors down the assembly. Look harder, you can still put more.

 

The height doesn´t allow more on the center..... Where can more be placed do you think ss?

PS: where did you get my SN before...

 

hey kaltmond: few questions

1) did you have to do any mods to the backplate itself?
2) what temperature improvements have you noticed
3) did you break a few of those heatsinks apart to make them fit?
4) did you use the normal adhesive of the sekisui stuff

 

1. I think not have to but better to do. Already doing it, will post later.
3. Yes, brake 2 to fit in the GPU main heatink. Maybe will brake more to fit in more places.
4. Now only used the original tape came with them. Just ordered the sekisui one.......lol
2. Average 5°C for CPU and GPU, room temperatur changes these days, so not accurate. But for a 3G Quad with nearly 0.1V overvoltage and a 65nm 128 Shader´s GPU it´s hard to get a low Temp in a small 15 chassis.....

 

yea, see... I'm only doing it with a P9700 (low-watt version of T9600),so I don't even think it'd be feasible to do.... What is a source (not ebay) to get those little heatsinks, and where can i find the sekisui that'll be enough to get this done?

PS: if i'm only using a dual-core with a 28w TDP,is it necessary to mod the case?

That's up to you to ask yourself. Do you want lower CPU temps?

 

I am watching with earnest, if we can get some temp comparisons that would be fantastic.

 

For a 15-inch laptop with one fan, you guys are definitely going to see an improvement.

 

Will see how effective they are when the sekisui comes. With a NC1000 the temperatur is really low now, compare to before.

 

How low? are we talking a drop of 10degs or more at load?

Im very interested to know, as im coming into summer here (40+ deg c nearly every day) and this is my first year with my notebook.

My desktop has alot of aftermarket cooling to help this over summer, and I think im going to have to make some mods to help the notebook cope.

 

ok, i finally did this based off kaltmond's pics. i used enzotech bcc9 memory ramsinks - http://www.enzotechnology.com/bcc9.htm

they are a little bigger and taller so i could only fit 6 on the sides of the CPU, 3 on each side and 2 on the GPU at the very top. i didnt mod my backpanel. i ordered some of the ones kaltmond used that are 4mm high, so i will fill up the rest of the empty spaces when they get here.

so far, my CPU idle went from 33-34 to 30-31, same room temp. i didnt do any extensive temp testing before i put them on so i wont have any exact numbers, but for the price i think it is working so far. i hope the GPU will go down when i load it up like kaltmond did his. ill put a pic too when its all done.

 

I originally had around 40C with CPU doing simple things like web browsing, or writing on word. GPU was also from 40C-45C. I got these temps after i installed the small heatsinks.

I took SS's recommendation of heatsinks being lapped, and also decided to renew the thermal paste during this. Once i put it all back, CPU temp at 30-32 with same simple things. GPU at 38. After playing some games for 1 hour, my max temperature for CPU dropped by 10 and also GPU by 5.

Im still lapping my HDD copper plate since its too thick and i dont have supplies to thin it down.

(room temp is around 26-27C by the way)

 

To what extent did you lap the blocks? Did you also sterilize both surfaces? What thermal paste did you use on your CPU and GPU?

 

Used the easy pc kit full sized lapping kit. Including the final polish compound. Lapped it so that i can see a nice light reflection without any clearly visible scratch mark from the sandpaper.

I did sterilize both surface using some alcohol. I was thinking of using the IC diamond thermal paste as my neighbor has it, but decided to use the AS5 i had with me.

Interestingly enough, when i removed the GPU and CPU heatsink, i was amazed by the ridiculous amount of paste on it. The CPU had this huge blob of paste all over the side, and the GPU had hardly any. (I did order AS5 when i ordered it so i am a little disappointed by how they applied it)

 

You guys should just rig up a phase change cooler to the cpu and gpu, then have it run off a portable generator duct taped to the back of the screen. That would be pretty extreme.

 

What I want to do is buy one of those crazy expensive solid state "fans" to replace the conventional turbines in our notebooks. Then we will have made it.

 

I hadn't heard about those until you mentioned them. Very interesting invention and I can see many real uses. Great stuff. I can already picture a gaming laptop with dual solid state fans etc.

Yes, those are the ones I was talking about. It's quite an impressive technology.
