MT860U Back/Bottom Panel Questions

I've got mine with open holes on the bottom panel.
But I was not pleased with temperature on HDD (54C).

So I've block other holes like on the pictures of the panel with closed holes for ACPI, RAM and bellow.

It was hell. I've got +12C on ACPI and 64C on HDD.
So this tapes which locking went holes are wrong.

Now I'm testing notebook w/o panel. If temps will be fine (right now 42-43) then I will just do a new hole infront of HDD as for CPU.

After some hours...

Okeys, so I've analyze the picture of air flow and blocked with scotch-tape 3 holes: vent hole, acpi hole and RAM hole.

Results shocked me.

I've tested on GTA4:
Results before: cpu 75с, acpi 87c, video 81с, hdd 64с.
Results now: cpu 59с, acpi 70c, video 64с, hdd 46с.

 

Where exactly are those holes?

Vent Hole: the one right under the fan?
ACPI Hole: ?
RAM Hole: Ok, that's clear.

 

Vent hole in front of cooler.
ACPI - between RAM and Cooler.

 

Thanks for your notes man,

Kindly clear something out for me. When first you said you blocked the holes as on the picture, do you mean the picture on the first page of this thread with black film? But it was modified there already. By defaul the fan vents were blocked as well as GPU and CPU were partially bocked closer to fan.

So what you've done towards the end of your post is what it pretty much was there by default. Except you probably left CPU and GPU exposed completely. I think I've tried that too but then there were not enough air take through the hdd hole. Again, this could really depend on your config and ambient temp.

My HDD now doesn't go over 53C under heavy load.

Cheers

 

Just out of curiousity, what are the makes and models and temperatures of everyone's harddrives?

Is this a brand specific issue, as many people don't have problems while others do.

 

Indeed.

Not sure, as I understood in the first post the picture of non touched panel from the right side.

Right, plus blocking cooler vent. Cooler hole is the biggest evil.

Here what I've changed...


Red squares shows what is blocked right now. It's not visible because Im using a standard scotch-tape.

 

That is a pretty significant temperature drop h0w1er! How hard is the fan working with those holes blocked? How loud is it?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

FYI:
Just to clear a few things up also. The first picture in the first post was intended to show the residue left after removing the tape because that was what I was initially concerned about.

Here is a photoshopped (quick and dirty) picture of what the replacement bottom case cover looked like when it arrived.


I think we can all agree that leaving all of that tape on, is a very bad idea as there are nearly no open vents for air to be drawn into the computer.
Hence BOTH Sager and Xotic saying to remove all the tape. (possibly a CYA move on their part, which makes sense)

However, removing some or all of this tape and/or covering different vents in an attempt to improve airflow and maximize cooling (which is what I think we are all interested in) is part of the fun of owning and modifying your own computer!

 

So am I understanding correctly, that blocking the three center vents will drop my HDD and CPU temps?

 

That's what the man says yes, but I recall seeying my temps drop when I removed the plastic underneath the GPU fan hole. I'll do some more testing.

 

Ok, something went wrong yesterday with temps again. I've played GTA4 again but with active Coolermaster Notepal for notebooks for ~6 hours, and I wasn't pleased.
ACPI was 98c... But HDD was ok, 49C after all these hours.
I'm a little bit confused now. I will try to play with opening some part of holes for ACPI today evening. But not with all of them for sure, otherwise hdd and wi-fi will die for sure.

 

Howdy,
This is what my film looked like by default:
GREEN are areas were exposed initially while RED is what I cut out myself.


Mind you, you are all free to experiment, I think I ended up increasing the opening over CPU eventually as well. But remember, the more openings closer to the fan the less air flow over HDD as suction power decreases. And if you are using an external cooler, it's better to expose all the vents.

Also guys, not sure if was posted before but check out this mod. This is by a French site Invasion Labs that sells overclocked customized Clevos, nifty:
http://portables4gamers.com/?p=7780

In their case the temps dropped noticably, but the openings are huge.


Cheers all

 

Oh yeah, there's some truth to that. I had a 2-3 degrees drop too on the cpu and gpu, but hdd temp went up 6-7C. So it was over 55C constantly, therfore I sacrificed a few degrees of my CPU/GPU to keep the HDD at bay.

 

Guys, cooled HDD is absolutely cool. But anyone care here about ACPI temperature? It's near 100c when RAM and ACPI holes are closed.

I've just did another modification.


In the idle temperature a little bit cooler then on previous mine. Later will test it with evil tool called GTA4.

 

Hmm, not sure why yours so high. My ACPI temp is always in between CPU and GPU temp. What version of HWMonitor are you using?

Not sure if you shold cover that vent at the top as it's part of the exhaust, not an intake. Try to have it configured as in my previous post picture.

Good luck.

 

HW Monitor:
Version 1.14.0
Driver version 132

ACPI is always around +10 higher then CPU. Nothing about between. I'm start to think that thermo sensor in some wrong place.

About top hole - exhaus, not sure. Cos it's below of exhaust, and this open hole sucking in the same hot air that cames from exhaust.


Static Space
I've tried as yours, the picture isn't became better.

ACPI 99c (I think it's not showing 100c) cos it doesn't know how. But for sure it's higher.
CPU 89c
Video 95c
HDD 48c

Better return back... At least CPU and Video wasn't so hight before.

 

Actually, you are right, ACPI always just a few degrees lower than GPU (around 4-5) But never above in my case.

Are you raising the rear of you lappy above the table surface for an inch? This will help a bit. Maybe it's you CPU that gives out so muc heat. Did you apply thermopaste yourself? might need a reapplication there.

Not sure abote that top vent again, I could almost swear it was part of an exhaust but now that you've stated I will have to check at home.

What is your ambient temperature? try opening all the bottom vents and keep GPU and CPU vents partially closed so that the air is sucked mostly from the cooler side of the notebook.

Cheers

 

The last modification:


+2-3C to HDD so it's like 52-53c on hard work.
But, 78C is CPU, 90C ACPI, 84C GPU.

The cooliest modification which I'm able to find for that "ohh, is hot"-CPU. It's like the best between "Do not burn yours HDD and rest"... Whew.

 

I find the testing you are doing very interesting, thanks.

 

Hey Howler, I checked again and you are right that top vent is an intake. Very odd but it is. I have tried to block is as well but did not get better results, slightly worst (1-2C above)

Ultimately I ended up having the same config as your latest, but all my midde vents and fan vents are blocked. I did open my CPU and GPU vents :] It raised my hdd temps to 50 from 47 but lowered respectivly by3-4C GPU and CPU.

30 min of 3dMark06 (no laptop cooler) gives me:

ACPI: 76C
CPU: 68-70C
GPU: 81C
HDD: 50C

So we kinda on the same boat here. Cheers.

 

I don't get it. You have such high temps with P series CPU?
It must be cold as ice

 

You know, I've been wondering myself.
When I'm not gaming and GPU is not loaded CPU is always 37, but the temp rises fast with video card. I thought maybe some heat was shared via heatsink by GPU.
Don't know what else to assume. Thermopaste seems fine.

 

lol, when I'm not gaming CPU are 37/36/38/37C... Quad... 45W....
So looks like P series is not a Messiah at all.

 

The 9800GT runs hot when playing a game (as verified from playing Far Cry 2), about 70C. The heat from the GPU tend to bleed over to the CPU and HDD(perhaps because of the 15" chassis?).

So my average temp between a P8600 and the QX9300 tend to be close-

As h0w1er mentioned, my idle temp for the quad is around 39-40C. I have consistently noticed even higher CPU temps from notebooks with lower clocks and integrated GPU(around 45-50C). So the processor type alone is not a guarantee for running a cool system.

 

70C is not hot at all... in fact, thats a really cool temp.

 

hi bro i need to check with you LOL
u see i m using a cooler which fan blow into the laptop (so i will blowing e dust in to)

do u think i should mesh? the area which got hole?

 

any1????????????

 

What cooler are you using. You shouldn't need to, most people only do so to get the most that they can out of it. I've seen little benefits though, maybe 1-2.C at most.

That's pretty impressive h0w1er, considering the lowest my X9100 has achieved is around 39.C, without a cooler. Do you live within the Arctic Circle?

 

hehe something like this, it cool alot and when i m on gaming it wont over heat 50C but it BLOW AIR INTO the laptop (so i will blowing e dust in to)

i use another one it will heat very fast and wont really cool down

 

Nope, 28.4C at room. As for Artctic, yes, not living but using their MX-2

 

Looks slightly like a Cryo. Make please?

Then that must be cooler-ed, or possibly in a room that defies physics.

 

?????????????????? dont understand....

 

Sorry mixing my words/coolers up again. It looks like the Enermax Aeolus, mainly because of the lighting gimmick. If it works that's all that matters.

The second comment, however, was aimed at h0w1er.

 

Maybe put the mesh over the laptop cooler--less permanent of a solution for testing purposes

 

go where to find a big mesh in singapore :/

 

You're the only one who knows Singapore best, harky. Look for one.

 

girlfriend's fishnet stockings?

 

..................
the hole is big!

 

LOL i bought a mash which is use to cover fan one...

 

How is it working? Any change in the temps harky?

 

can try DAISO mah....use the mesh for cooking instant noodles one...hahahaha

i go daiso once...got so many household $2 things that you can modify
using a little creative minds , get it done alrd..

 

same... as i cover the cooler not the laptop

 

Here is a pic of my backplate:



I've noticed that on the area's where there are hole strips, not all of them are "punched" through, sorry but do you get what I mean?

For example, the holes of the backplate directly above the Northbridge heatsink are not completely punched through.

 

o i see but what are u trying to say? :/
isit mean dust protected?
kindly worry as i had alot of dog fur

 

I mean do I still have to punch through those unpuched holes?

 

You can if you want to, but it's not going to yield any difference.
