Asus G1S removing tape temp drop (stats included!)

If you remove the cpu lid cover, there is some black tape covering the air holes. Upon removing this I noticed you get a considerable temperature drop. (I left the copper colored tape on).

---Tape still on, cover on
cpu max undervolted - 84
cpu max stock volt- 96
cpu max T overclocked - overheat

-- Tape removed cover
cpu max undervolted - 77
cpu max stock volt- 92
cpu max overclocked - 96

--- open cover
cpu max undervolted - 72
cpu max stock volt- 78
cpu max overclocked - 80

Upon removing the cover entirely the temperatures drop even more. This is for my t7500 running at 2.2GHz @ 1.250V standard, 1.050V undervolted, and 2,4GHz @1.250V when overclocked. The cpu was stressed using orthos, temperatures measured with RMclock and confirmed with hwmonitor.

As far as I could tell this had no effect on gpu temperatures, mine still maxes out at 97°C.

 

Yeah, we already know that.

The bad news is that the hdd temperatures increases a lot, so does the wifi card and the RAM.

Not worth the trouble IMO.

 

Took it off myself once and put it right back on. The HD section felt like it'd melt. This G1 case is quite an old design, it used to be used in the A3000 which didn't have chips that are as hot as the 8600M GT GDDR3 in it. Instead of designing a new case I suspect Asus cheaped out and crammed everything into this case here and tried to do a little tweaks so that it doesn't melt down.

 

How does this affect the hard drive? The airflow should be better how can this negatively affect the rest?

 

Yeah, the HD does feel pretty hot now that I removed it. I think it's because the air is now coming in the middle and being sucked out the back and it's bypassing the hard drive. Are the hotter temperatures going to affect my hard drive at all? I didn't see much improvement in the GPU temp. When you say you opened the cover do you mean the lid over the GPU/CPU? Won't that let in all kinds of dust and crap? Do you really use it like that?

 

well , i dont see an increase of hdd tems removing this...

96 C CPU???, my max temps were 82 with oc... a t7500 @2,4.,

try to change thermal compound ^^.

 

The removal of the tapes does indeed increase the temp of the HDD bay and the RAM/Wireless bay. I think this is because there is some kind of internal airflow that is being disrupted when the air is drawn from the CPU/GPU bay.

This is probably why the tapes were there in the first place. However the benefits seem greater than the losses.

My HDD is operating lower than the specified max operating temp of 60C and same with the RAM (70C) and the Wireless Card (80C).

 

just curious, how do you measure RAM and wireless-card temperature?
I guess you'd have to use thermometer and touch the components, as they don't have any temperature sensors built in, right?

 

Yeah, I used a thermometer. It's not 100% accurate but you can get a rough idea.

 

well, i think that the power of the g1s fan is not enough to make an internal airflow...

my hdd temps without cooling pad are 45C (hitachi sata 160gb 5400rpm),with and without tapes.

But can be an interesting idea drill some holes in the hdd case ^_^

 

Do you have any other modifications? Are you using a cooling pad?

There is obviously temp changes to both the HDD area and the RAM area, many users have noticed this.

 

well i change cpu thermal compound , gpu thermal compound, apply thermal compound to VRAM and chipset, but nothing that make the HDD more cold ( I´m thinking about drill some holes in HDD case i the future).

without cooling pad: 45C
With cooling pad : 38-40C


Well i didn´t see RAM temperatures... but the hdd temp is the same with and without tapes, but I use to use the Notebook with a cooling pad (this http://www.pccoste.es/comprar/ofert...egro.aspx?bn=&pedir=&parpanc=1338&parpalt=754)

then I think that ram temps will be lower without tapes, because the airflow goes to the RAM directly.

 

It's strange that you don't see any variation in the HDD temp.

What would be interesting is to see what the bottom of the new G1Sn is like to see if Asus has kept this horrid cooling design!

I will investigate my HDD/RAM temps some more. My current theory is that the GPU fan is strong enough to pull air through the RAM and HDD grills.

If I replace the CPU tapes then only the HDD temps rise. If I replace both the GPU and RAM tapes, temps are back to normal.

This seems to indicate that there is some minor internal airflow. Another thing that is that, when I have the tapes on, the right side of my keyboard is a lot hotter.
