And speaking of laptop coolers - are ANY of them worth buying? Reccomendations?

I use the Antec usb powered dual fan one. It does seem to help somewhat. Bit loud though.

BTW this topic has been thrashed to death many many times so we might wanna move this to one of the existing threads.

Nexus TDD-3000 notebook cooler

For those of you thinking of purchasing this cooler----BEWARE. If your notebook has "feet" that set it up so that it will not rest on the aluminum of the Nexus cooler, then it simply becomes a notebook stand. I have a Fujitsu N5010 and wanted to try this cooler since it uses no power and makes no noise. However, the built in (i.e. molded) feet on the bottom of the laptop elevates the machine from the aluminum pad....leaving about 1/4 inch air gap. Given the description of the design of the heat pipe cooler, an air gap doesn't seem to fit in that program.

Since I think I could cook an egg with my laptop before and after using the Nexus, I would say that air gap is an effective barrier to the heat pipe technology.

It was a great idea while it lasted, but I think I have to send the heat pipes packing and trade for a fan (i.e. noise) based cooler.

I have a 4780 and I used the nexus cooler for a bit before I ebayed it. My 4780 also have the little feet so the cooler did not work for me. I am now using a dual fan aluminum laptop cooler that has its own power and also acts as a usb hub and its been working pretty good. The fans dont come on as frequently and when they do, its for a shorter cycle.

Sorry, but I change notebooks almost as often as I change my underwear.

I have neither the Sager nor the cooler any more. See my sig for my new rig.

There is another thread floating about in General about the cooler you speak of, and it has many many pages of posts so I think you'll find it helpful. I am buying one this weekend as many people have said it works fine for the 5690 een though the 5690 has feet at the bottom. This is because the heatpipe tech cools the air directly below where air intakes are, thus the air being sucked in is of a lower temp, and thus the laptop is cooled. One of the things that heat up 5690s is that it warms the surface it is on, and thus air being sucked in is warm, and thus the laptop gets hot. Heatpipe tech does not need to be touching the laptop to work.

I use the iCurve stand.

40-42C without it (idle)

35-37 with it (idle)

just gets the distance from the table the fans need to do their job.

wazzup, when I get mine, I'll do some tests. I have an 8890 with the little feet and though people speculate the little feet will mean it doesn't work (in 'that other thread'), there were some with actual experience (Nandro and n666z). Just gotta wait for it to get here... via UPS

I hate to bust your bubble but it DOES NOT cool the air. I ended up ebaying mine.

Well, from testimonies of people with 5690 and bought the cooler, it does work... I have yet to try it, but will be buying one this weekend, so we shall see.

Agree - technically.

Physically it causes the air to be cooled by mixing cooler environment air with the air around the laptop at a higher rater than normal convection?

When the air that gets "sucked" into the laptop is several degress cooler, the laptop ends up being cooler.

yeah the whole point of the heat pipe technology is metal on metal action. heat travels the quickest through metal which is why those coolers are meant to be put flush against the bottom of the lappy otherwise they dont do much.

I'm going by people's reccomendations - people that have the product and have a laptop with feet. They say it's noticably cooler, so I ordered one. As soon as I get mine, I'll do some tests and we'll find out for sure.

I'd never recommend the "metal on metal" scenerio. A bit of spacing provides an oppurtunity for enhanced air mix and results in cooler temperatures. Now, for heat syncs, the metal on metal with AS5 is recommended - simply because the heat sync is being used to transfer the heat into the air flow.

The Nexus cooler did nothing for my 8790. However, it worked well with my old HP laptop, which has a 5690-like chassis.
