Road Worrier Tests Out Chill Mats


Chill mats — notebook stands or rests with a built-in USB-powered fan to keep your machine cool — can be handy if your laptop tends to run on the warm side, especially in the summer months. But making them work with a PC that’s constantly on the move can be more of a challenge.

In the past, I’ve been sceptical about the usefulness of chill mats. This is what I wrote about them two years ago, back in November 2008:

While overheating can definitely be an issue, I’ve always found chill mats more hassle than they’re worth. For one thing, they put the keyboard at the wrong angle for my liking; for another, they’re too bulky to throw in my laptop carry bag.

Circumstances change. These days, I constantly use a chill mat in my home office. The main reason is because my 18-month old Portege notebook is running very hot these days, occasionally to the point of actually shutting down with heat failure. Yes, that’s a clear sign it needs replacing, but I want to squeeze a little more life out of it while I can.


Logitech Speaker Lapdesk N700

Despite the “lapdesk” name, I’ve never found the N700 comfortable to actually rest on my lap: it’s a bit too bulky, and there’s an uncomfortable ridge at the top edge. It’s also way too large to use anywhere except in my actual office. (The overall size would certainly be handy if you had a larger notebook screen, but I’m firmly in the sub-13 inch camp when it comes to notebooks, since they work better on planes and in my luggage generally. The N700 is too large to even qualify as hand luggage.)

So over the past couple of weeks, I’ve been testing out three different recently released chill mat models to see if they can be of use when I’m on the road, or even just working casually in front of the TV. This isn’t an exhaustive selection of what’s on the market, but it does give some idea of the diversity of design that’s out there at the moment.

Just how much difference a chill mat or fan will make to your overall heating performance varies. Even if your machine doesn’t run particularly warm, having something between your laptop and your bare legs is often a good idea for health reasons.

There’s one undeniable issue with all these products: there’s a noticeable increase in noise level when you attach a chill mat. This is a lot less obvious if you’ve got some music playing, but it could make a chill mat less than ideal in, say, a library. With that said, I prefer the constant low-level hum of an external fan to the dread whining sound that comes as your processor and on-board fan fire up when a particularly CPU-intensive activity kicks in.

  • Ive got a zalman cooler for my 17″ studio, and while its great for woking while on desk or at a table, the frame really digs into you when you try and lap it.

    Its aluminum and plastic so its not overly heavy but i think its really just par for the course with most laptop coolers, if your going to lap it theres going to be increased airflow around it anyway, and personally for me, my productivity falls off the charts when i try and work with it in my lap
