W860CU Cooling vent covered; accidentally?

I just opened my laptop to clean the fans off dust and found something weird...


The left vent is covered with some kind of plastic thing.

Here i removed it:


Was it a mistake to remove it?
Now it seems identical to the right vent except that there's no soft foam around it.
Could it be that they had forgot to remove that thing before shipping it to me?



Another question; is it a bad thing to have plastic flags covering the heat sink?
There's one flag on each heat sink and they say not to remove them... but don't they kind of prevent the heat sink working to full potential? should i remove them anyway?

 

if you bothered to look at the 8690 thread, most of us have to remove it manually, though some reseller had it removed before sending to user.


removing it is best choice as the gpu temperature will definitely lower down.

for the sticker on the heat sink, you need it to pull the heat sink when you are applying new thermal paste or changing the hardware below it.

 

+1 The stickers would only affect the heatsink if it were over the fins, which it's not.

 

Hmmm i don't understand why was it there in the first place, or more importantly; why wasn't i told about it..

I don't know how exactly heat sinks work, but better ask before act right?

Thanks for the help

 

Heatsinks work by transferring the heat from the CPU or GPU through aluminum or copper pipes to aluminum or copper fins, where the heat is dissipated.

Edit: For some reason it was in my mind that the laptop was an X8100. I should stop playing TF2/helping people on NBR at the same time. Sager has said it's there to help redirect airflow. The whole reason that was left on is (in my opinion) simply a quality control issue. As genocidew said, some resellers don't remove it and some (usually system builders, as they actually open the case to build the product) do.

Edit: If you're interested in knowing about how heatsinks function, there's a great article here: Info: How does a heatsink work? - Overclock.net - Overclocking.net

 

But that is a W860CU, which is not SLI. Well, thats what his sig says.

The existence of that sticker baffles me. It is absurd. Why oh why is it there (sometimes)? I don't get it.

 

For some reason I had it in my mind that the laptop was an X8100. My mistake! Sager has said that it is used to route airflow to the rest of the case, but I think it's just from when Clevo ships the laptop to help reinforce the mesh and they forgot to remove it.

 

I believe the vent that was blocked takes air in, because there's another vent on the side of the laptop which blows hot air out.
Speaking of which, the left side which had the plastic thing on, was usually blowing out more hot air than the right side.
At the moment it's cooler.

edit
Also there's 4 vents, 2 fans.
2 vents blowing air out from both sides of the laptop, and another 2 taking air in.

 

There are always more vents than just the ones above the fans or there should be.

The memory gets pretty hot, but there is room and power for one more fan so if there is a problem Clevo could just have installed another small fan - that they did not do so there cannot be a problem with the memory heating up a little bit.

The problem is that the CPU gets about 10°C - in my case nearly 15°C - hotter with the sticker. While 78°C max temp is still a good temp for mobile CPU the situation changes if we speak about i7/i5s. With the sticker my CPU does not always use the highest possible Turbo Boost multiplicator, without the sticker it does. So if your using the sticker you potentially throw away performance, performance you paid a lot of money for, so this whole sticker thing is a cheek.

Even if there is a minor problem with cooling, potentially throwing away performance is not the way to go with a high performance laptop.

 

I'm just surprised how you just recently discovered the sticker

 

Well i can't exactly see inside the grill without a light, like i would spy in there in the first place

 

I just opened my Clevo just minutes ago, and there was that stupid sticker. I removed it, hope the CPU temps will be less.

 

I thought the sticker on the cpu heatsink was to help me lift the heatsink up.

 

congrats!

All CHN w860cu players remove this stupid sticker ， just like what you did .

information from official CLEVO factory , shows the CPU temp is 5 Celsius UP when the sticker is on . this result is correct and consistant with my test .

please read these pictures first .

pics shows that CLEVO up the CPU temp and exchanges the other parts' temp down .

how stupid it is !

When we China player have got the W860cu the first thing is to discard the sticker .

we have many methods to make the other parts' temp down but we think the cpu temp is more important than hdd etc.

we can use a thermal pad at home when we play games , and in office that's not necessary because all parts work in a NORMAL temp .

 

x7200 still cover a stupid stick .

 

I have seen it mentioned before that this being left over is often deliberate, and not just from Sager; as it forces increased airflow over other components, resulting in a cooler overall system, whilst not massively increasing temperatures for the CPU.
Take that as you will.

 

Not like it's a pain to test it out.. Leave in, do some stress tests or benchmarks.. Take it out, do the same. Report back with screen shots of hardware temps

Idk about taking the sticker off though, kinda seems like it's used for removing the heatsink. If it was causing that much of an issue with heat, dontcha think Sager wouldn't have put it there? Just my thought

 

CLEVO told us :"

we tested this sticker a million times in the hydromechanics laboratory which worth millions of $$$.

so , you'd better do not remove it because this sticker could keep a right-way airflow , and it will make the other parts' temps down .

"

I wonder : many w860cu user use a SLBLW/q3b8 or SLBSC/q4ap cpu ,
but somebody told us w860cu can't use this 55w TDP cpu only because 860cu's heat sink NOT support high end CPUs.

but in fact 860cu uses copper fins better than P150HM's aluminum , my 840qs(q3se) never touch 60 Celsius (game play / mkv 60fps playback) , what a powerful cooling-system , but wasted for the sticker.

I'll buy a 920xm retail (SLBLW) because in China it's only 545$ .
920qs（q3b8） only 290$ .
so I must remove this stupid sticker.

CLEVO also order us :

if we wanna upgrade to 920/940 , we should buy w870cu .
if we wanna upgrade to 480 , we should buy w880cu .

all is stupid , CLEVO did so many wrong things .
include they don't update a EC/BIOS for us so we can use a 485m GPU .
(in China gtx485m can be easily got , everything outflows from the factory )
also include this stupid sticker .

if my 860cu was destroyed by removing that sticker I'll tell you my friends .
otherwise please remove it , at once !
