Discussion for cooling the 6625wd

After the news that an aftermarket internal cooler for the 6625wd
wasn't going to happen, I thought it might be worth seeing how the
rest of the 6625wd users cool or plan on cooling this beast.

Please, if possible, post your solutions with before and after temps.

Are the temps from your HD? CPU? GPU? Give details!

I'll post my finding for the Zalman ZM-NC-1000 later this afternoon
when my wife is finished using it to cool her own 6625wd.

 

I usually just place the back of the notebook on top of something that's 2cm high, that way the air can flow out from underneath the notebook.
My temps go down 5-8c degrees whenever I do that!

 

Iv built a custom cooling pad of lego wich makes the lappy tilt a bit, but I havent noticed any change in temps (as I only use the cooling pad at home, not at the cottage). As I said in this thread Im going to test to have it open and run it to see th temps.

Currently my temps are (light use/gaming):
CPU 50-57C / 75-80C
GPU 60C / 90C
HDD 30-35C / 35-40C

 

Just finished testing the Zalman ZM-NC-1000:

Conditions: No programs running except Rightmark CPU utility to measure
CPU temperatures. Each 'section' was tested over 20 minutes with the
lowest temperatures being reported. Each stage was tested directly after
the previouis stage.

Stage 1... 51C...Laptop unused for 30min, no cooler attached
Stage 2... 48C...Laptop on cooler, cooler off
Stage 3... 45C...Laptop on cooler, cooler set to lowest setting
Stage 4... 48C...Laptop on cooler, cooler set to highest setting
Stage 5... 47C...Laptop back on desk, no cooler attached

I believe more pronounced differences would be shown under heavy
cpu/gpu usage but that's just a guess. Interesetingly the temps increase
when I increased the fans speed! I believe this may be due to undervolting
the computer but I really am not sure why this occured. I never observed
any harddrive use save an occasional 'flicker.'

From this test, I'm encouraged that a "passive heatpipe" cooler would be
ideal for an undervolted 6625wd.

Hope this helps!

 

It might start to compete for the air that they use, leading more air around the laptop instead of trough the heatsinks inside the laptop

 

That's a good thought, I know the Zalman 'blows' the air rather than
sucks it, so it seems logical. Depending on intrest and ideas, I'll do
another test perhaps next week. Love them legos! Looking forward
to those tests!

 

Hmm not much of a difference ? It makes the temps go down about 2-3-4 degrees ? That can be done by undervolting CPU... I don't see why you should buy a cooler, when it doesn't do its job

 

Agreed, but this laptop is already undervolted so the 'belief' is that drawing
more power from the usb is somehow causing the computer to warm up a
little. Thus, an ideal would be:

Undervolted 6625wd + PASSIVE coolers with heatpipes.

But that's just a guess... we've had the Zalman for awhile now to keep our
old Znote 4200 cool but since we had it already I thought I'd test it for
anyone else interested.

 

They do cool, some of them up to 10C full load temps, just not all of them

 

I don't know about the 6625wd, but for the 3415w the cooling is temperature reliant, meaning if I used the notebook cooler when the computer is idle, it will simply result in the internal fan completely shutting off and the notebook cooler doing the job, meaning it will still be around 48-50C anyway. The real use comes when gaming, especially if you overclocked the GPU.

 

Besides Passive Heatpipe coolers this seems like another solution, but
far less elegant: Refridgerator Cooler

I imagine if this could be retro-fitted it would definitely do the trick for the
6625wd. It's just a matter of redirecting the air flow it would seem.

 

I have around 15 degrees in my room atm... so the comp stays cool.

 

Hehehe, there's dedication to cooling your laptop!

 

15 degrees ?? You live on the North Pole ?

 

+15C is nothing, just wait till it gets a bit colder up here and Ill be in an room wich is on the negative side of 0 xD

 

Lol, be sure to get a coat for your notebook

 

It's already 2C here in Stockholm... and dropping!

Just ordered this: Passive Heatpipe Cooler

It's anyone's guess how long it will take to arrive but as soon
as it does I'll let you know how it gets on with the 6625wd.
I'm anticipating better results with an undervolted computer
than with a normal voltage+fan cooler combo... stay tuned!

 

Hate the scandinavian winter, so cold But the snow is yet to come... yay

Yeah please give a little a review when it arrives

What's the price on that cooler?

 

Do post results, seems quite intresting to have a passive lappycooler

 

Actually, I wasn't given a price. It's just a local guy I go through, but he'll
give me one as soon as it's in (of course.) Will give a basic review like the
previous one (see above.)

Remember though, this isn't a 'normal' passive cooler, it has heatpipes
instead of air channels like most passive coolers. Stay tuned!

 

Haha.. no... Irleland.
I am here temporary for a job. And my landlord tries to save money bu not having the heating on during the days. Were 12 degrees some day ago.

 

dang! Some landlords huh....

 

Manufacturer's Link: TDD-3000 heatpipe notebook cooler
US link: Nexus Notebook Cooler TDD-3000: 36.95usd.

No good direct links yet for EU / Scandinavia.

I'm still waiting for mine to arrive, might be after the new year.
I did learn that the space between the cooler and the laptop
bottom is critical for maximum benefits from the heatpipes.

UPDATE: Confirmed from my supplier that it won't be until
after new year when cooler comes in. Stay tuned...

 

Researching various cooling methods I came across yet another
interesting doo-dad: Memory Heatsink.

I believe this particular article is for traditional memory and not
laptop memory but thought I'd throw it out there to see if anyone
knows anything about this and if it's applicable or even reasonable
to try in a laptop.

This one is from the same manufacturer of the laptop heatsink cooler
mentioned in this thread: Memory Heat Spreaders.

 

Just a quick update as I noticed I provided confusing links before,
so here are the links to the 2 different passive heatpipe coolers:

(1) TDD-3000 (Nexus)
(2) T3000 (ThermalTake)

I've ordered the second one, from ThermalTake and I'm told it'll arrive within
a week. As before, I'll post the results as soon as it arrives.

 

After waiting for over 3 weeks, I cancelled the order, sorry all. It was
taking just too long and what's more, my docking station arrived. It's
worth noting that even a large or oversized cooler won't work with the
docking station.

I knew this was going to be the case, and hadn't planned on using them
together. If you were to try and use them together, not only would the
setup be too large for coolers, but the docking station itself creates a
noticeable angle to the laptop, basically lifting it's back end off the surface.

Oddly, this should help cool things down a little, so might be worth
looking into for some.

If enough people are interested in hearing about the docking station
in combination with a 6625wd, let me know.

 

Well it would be interesting to see the results but I wont ever buy a dock for mine thou

 

Yeah, thus far only 1-2C difference under light load.

Unfortunately I can't recommend the docking station
at the moment, as it doesn't 'dock' (mechanically
speaking) very well and the speakers it comes with
seem to pick up frequency noise. So far 2 out of 5
stars... but have only had it 2 days.

I'll be purchasing a glass desk in the next 1-2 weeks,
lets just see if that helps!

 

after playing COD4 a while my machine begins to overheat. which is extremely annoying and this is a notebook advertised as a gaming machine.

 

Though not necessarily directed at just 6625wd users, a docking station +
glass table top (wood underneath) combo results in a 2-3C drop in temps.

Resting Temp: 46C
