Has anybody used one of these or anything similar? http://www.cybercoolerinc.com/nk-360.html

It is a slab that goes underneath the laptop and cools it with three fans. I'm looking into buying one, any help/comments would be appreciated! Thanks!

Actually several threads have been put up about those very units. They will help, you might try looking through the older threads to see what was said in them. I built my own cooler mod, lol, because I didn't want to buy one :-) but they will definitely help keep the lappy cooler in places where it would otherwise be difficult (your lap, for example).

i'm using one of these Coolpads http://www.roadtools.com/ after seeing one on my prof's desk ... had to check it out. it doesn't have any "Active" cooling like extra fans or anything, it does give a nice angular boost for typing and viewing, however, and the base swivels 360 degrees. you just sit the laptop on it.. everything has a very good gripping end (both top and bottom) and there is no slippage whatsoever.

i'm kind of interested in seeing a liquid cooling mod for the 8886 series someone make one i imagine there is not a lot of free space inside the case.

"Last year a CoolPad user from Seattle told us that in the aftermath of an earthquake about the only thing that survived was has laptop on the kitchen table sitting on his CoolPad."

That earthquake must have been localized in that CoolPad user's house, because I live 15 mins outside of Seattle, and we haven't had even a small quake in a couple of years. The last one we had (Almost 3 years ago, I think) would have been hard-pressed to destroy everything in his house but the kitchen table and his CoolPad. I'd be much more interested in purchasing such an indestructible table than the pad itself in any case.

I have this thing.

Quite honestly, it's not really necessary unless you plan on using your 8886 on your actual lap.

It's not a robust enough solution to make a difference in a sever overclock. Since the 8886 has such good cooling, it won't make a difference w/ minor overclocking. Okay, so you might get a 2% increase....

But I'm using mine right now. I know heat is generally bad for electronics and you put the odds of something bad happening in your favor by a bit more by keeping it a bit cooler. I wouldn't call it loud, but it does make noise. Still quieter than your average desktop tho...

So get it from www.newegg.com if you want it. It was $17 and newegg is about the best high-volume electronics dealer you can use.

Heat is definitely bad for electronics... once wiring is hot, you start losing signal and current and voltage to resistance and making more heat... Basically, efficiency drops way below par. To put it another way... if the fans constantly blew while on battery power (as in even when they aren't needed)... I would let them run even if it used battery power rather than make them run only when necessary. You will prolly save battery power (or at least break even) by avoiding battery loss to heat. Honestly, I don't think that is exaggerating... Someone correct me if I'm wrong, lol.

Please correct me if i'm wrong, but wouldnt this product actually be counter-productive for a 5660 since the 5660 actually intakes cool air from the bottom whereas this product is supposed to help remove heat from the bottom of a laptop? Unless the product can be reversed so that it blows cool air into the bottom of the 5660.

No, I don't think so. Both the lappy fans and the pad's fans will pull air into the space where the lappy fans suck it into the system. The pad will help to assure that the air sucked up by the lappy is always cool. Also, the pad lifts up the lappy even more for better air flow.

Like I said, it's only really necessary when using the lappy ON YOUR LAP. Other than that, b/c of the excellent cooling of the 8886, it's mostly unessary.

But it isn't hurting anything, except maybe putting a small dent in your wallet that one time....

other coolers

Do you think that this would do a better job?: http://www.byteccusa.com/product/cooler/nc-500.htm

Is is a little bit more expensive, but would the 8886 fit on it? it sems a little too small. Also, while on the subject of stands and the like: what about this notbook stand? http://www.lapvantage.com/dome (I'll be using an external wireless mouse and keyboard) Thanks

Hey, if you've got money to burn... get it all.

About that other aluminum cooler-thingy--it looks like the fans are exposed on the bottom, which would defeat the whole #1 use of the cooling pad (typing on your LAP). Also, the incline of the thing isn't really value-added IMHO (due to the excellent cooling of the 8886). I'd go w/ the plastic one; works better on your lap.

regarding that I-Mac-looking thing... pretty cool, but your 8886 will hang over the sides a bit. It won't look as cool as it does in the picture either b/c you'll have cords running everywhere. Even if most things are wireless, you'll still have wires for the adapter. Unless maybe you go IR... But that thing does look really cool.

Either way, I don't think the first thing will work w/ the second thing--you'll have your lappy sliding off into your lap!

First, Investorguy, I love the signature :-)

And second, does the cooler blow air into the area on the the lappy or does it suck air out? That would make a big difference actually, because sucking air out would be counterproductive. Though as you said it is helpful simply in the fact that it raises the thing. And again, the lappy is so well designed that those things aren't necessary unless you are putting it on a surface where the fans are blocked (your lap or another soft surface).

how does sucking air out make it counterproductive? wouldn't it move the air inside the lappy faster?

If the fans in the lappy are sucking air from under it and blowing it out the side, then fans on a cooler unit sucking air out would suck air away from the lappy's fans. It would be like putting two room fans back to back.... not going to work well.

no beeb, I disagree. Both fans would be 'sucking' air from the same place--between the lappy and the cooling pad.

I'm no physicist (unless reading Michael Crichton books counts for something), but I believe that since the displaced air has to come from somewhere, the airflow *between* the lappy and cooler would increase as both fans sucked air from there (the between space). The only way it wouldn't work is if there was some kind of vacuum created by the two sets of fans. In our case, 'new' air is sucked into that 'between' place (from outside the lappy environment) as the older, hotter air is blow out the 8886 vent on the right and the cooler vent in the back.

Gosh, re-reading that practically confuses me (and I just wrote it...)

Whatever; yeah, I could be wrong... Perhaps your pre-med better equips you w/ physics than a finance major....

I guess both make some sense, but I think if one sucks air out and one sucks it in, the one that sucks it out takes away some of the in that the out took out.

What?

But the real questions is: how much out would and in suck in if an out was sucking in and not out?

Heh-heh, figure that one out! (or is it in?)

hmm.... if enuff air is sucked in opposit direction and the "new" air doesn t replace the space of the old air underneath the laptop in a fast enuff time. i believe a spacio-temporal void could be created and thus, according to Albert, could in turn create a mini black hole just between your lap and the Sager..

Hmmm,

Then your privates could be in an infinite number of places at the same time, possibly coming into view through a portal of the Starship Enterprise travelling at Warp 9!

lol, I went to bed last night and now I'm back and what is written here is hilarious :-) In any case, I see where you are coming from... I guess it all depends on the surroundings. That's a simple way to settle it I suppose :-)

hmmmm,

Quantum mechanics could be the solution to have a cool down laptop then...but only if travelling at Warp 9.2 ( you have to take in consideration the variable that is the thickness of the pants or the Shorts were the laptop could be infinitely seating on...virtualy speaking of course)
