Laptop Cooling Pad - Important/Worth It?

Teeklin 38 10 September 25, 2012 at 04:17 AM
I recently purchased a new Lenovo Y580 laptop for work and it's awesome. I do notice, however, that sometimes after using it for a few hours and packing it up, the desk it's been sitting on is exceedingly warm.

I was thinking about getting a cooling pad for it to sit on, but I really don't know anything about how effective they are, how much I should be looking to spend, and what the best one on the market is.

Any thoughts or advice would be much appreciated. Thanks!

Any cooling pad with the right size and fan(s) will do the trick. $5 is the low price point for them. The problem is how loud the fans are and if the USB connector (for fan power) is bulky that could obstruct the nearby USB ports.

search the past FP deals by using "cooling pad" as keywords and you can read others' reviews for different products.

The cost isn't really an issue, just curious what a good one runs. I spent $1000 on a laptop, so if it's important to have one I'll spend whatever I need to.

And I did a search for them and saw so many deals that I had no idea what I was even looking for. Really hoping for a personal recommendation from someone who has and loves theirs.

I don't like the Cooler Master one I bought - LINK [newegg.com] - the fan has a bad bearing, developed it about 30 days into using it. Too much of a hassle to try for a return. Sometimes the fan will stay on when you shut the laptop down too. I would advise against this one.

I have used this one before - LINK [newegg.com] - and I like it. You can move the fans around, and it is a solid-feeling cooler.

On the whole, I think laptop coolers work a little bit. Like you, I use one just for the peace of mind. Plus I tell my wife she *must* use it, because she has a habit of placing the notebook on her lap while using it. The fact that it is on a cooler/pad helps to elevate the PC just a little bit.

The hot condition is not normal and cooling pads can be harmful to the laptop, for the additional current that the laptop is forced to supply to the USB ports in which the pad is plugged into.
When you have an old clunker that you don't want to spend any money on, and it's running hot because the fan is old and tired, congested with crud, with a slow hard drive that has to work twice as hard to do the job, then yes, a cooling pad could be a good idea.
Otherwise, it's out of the question for any new machine.

As sure as I am sitting here, that Lenovo could run way cooler. just by being properly tweaked.
And that is what you should devote time and energy on.
Open your task manager, a couple of minutes after booting up. without opening any programs or browsers. If you have more than 60 processes running on that baby, then you know that it's working hard for nothing, and it's time to tweak that laptop up.
There's more to a full tweak than just stopping unnecessary processes from running, but it would probably make enough of a difference that you wouldn't be yearning for optional cooling options.
If you do have 60 or more running and you don't know how to do the job, just say so and I/we can walk you through it.
BTW: If you have 70 processes running at an idle, that's pretty bad. If you have 80, that's real bad. If you have 90, you're frying your machine and contributing to its premature death.

If the laptop normally sits on a desk or flat surface, you would be fine just propping the back end up a little for better air circulation. What I normally recommend for a quick/easy solution, is just to get one of those large, rubber bouncy balls from the candy machines (~$1), carefully cut it in half, and use double-sided tape to adhere them to the bottom rear of the laptop which elevates it.

The reason for this is that in the push to make laptops smaller and smaller, the tiny rubber footings on the bottom usually do not allow for adequate air flow from the exhaust/intake (depending on how yours is configured). So even just raising it up 1/2" or so dramatically decreases the amount of heat buildup under the laptop...which also raises temps inside the laptop.

Cooling pads with fans are pointless to me. There's usually only one large opening on the bottom of a laptop for heat to escape, and that large opening already has a fan in it exhausting the hot air. No matter how many 120mm fans you set your laptop on, it won't make the heat come out any faster than what the internal exhaust fan can pull it out. And even if they are intake fans on the bottom, the same rule above applies. The only reason that you will see a temperature drop with these is because of elevating the laptop so the air isn't restricted, which is what the rubber balls do...but not because of the fans. Just my $0.02 on this...to each their own.

"Exceedingly" warm means too warm -- beyond official specifications or hot enough to damage the computer or cause operation to become unreliable.

Generally the only time you need a laptop cooler is when you use the laptop on your lap because that usually blocks the ventilation openings.

Just find a way to rise the laptop bottom by 1/2-1 inch to increase air flow. Someting like 2 large chop sticks.

Transistors/Chips use less power at lower temperature.

this GTX 480 test [techpowerup.com] shows every ?C that the card runs hotter it needs 1.2Watt more power to handle the exact same load.

try the Antec Notebook Cooler Basic, it doesn't have a fan, transmit heats much faster than wood desk. myself don't like fan's vibration, so i recommend passive cooler. ( i just checked the price, seems it's discontinued)

laptop runs cooler -> laptop fans runs less/slower, so it degrade slower(old fan makes more noise&vibration) -> laptop use less power -> charger runs cooler(longer battery life if using battery) -> charger last longer under lighter load.

it's almost unnoticeable if compare to a power hog video card, but facts are facts.

I have an AMD HP laptop so I know something about heat. When I first got it and ran it on my lap, thought I could burn from it. Had it cut out on me a few times due to heat rising past 100C.

I invested in theCooler Master U2 [newegg.com] and it's been great especially since I got them for free after rebate last year. I have 2 little 80mm? fans pointing in to the inlet under my laptop and it's been great at keeping my heat under 80C most times. I got 2 of these for desk and when connected to the TV in the living room. I was also able to pick up some more 80mm fans by purchasing the U1 when they were FAR so I have 3 fan on my coolers. It works well but does get dirty due to dust and such.

I regularly vacuum the exhaust outlet of my laptop as well as the fans b/c they can sometimes have dirt dust build up and make noise. Heat stays around 74C and when I see the heat nearing 80C I vacuum and it's good to go for another 3-6 months.

I've tried about 6 laptop coolers so far and like this setup the best. I didn't like the D-Lite or the X-lite from CM as much like another person said. It's big but doesn't feel like it moves alot of air and it's just pointed at the bottom in one direction. Not as effective as small ones pointed directly towards the intake.

If you're talking about an HP laptop from several years ago (approx. 4 to 6 years ago), when HP made a bunch of hot running machines, then I would agree with using a cooler pad, as those machines have an actual design flaw and no amount of tweaking can get them to run cool, specially as they get older and the hard drive has to work harder and the fan gets a bit slowed down with age, but in the OP's case, the brand new Lenovo is NOT a hot runner and solving the heating problem would be much better than using a Bandaid solution, don't you think?

Was debating on getting a similar Lenovo model but decided on an HP instead. Anyhow, I use a cordless thermal gel cooling pack [amazon.com] that does just fine for everything I need in regards to cooling. It does thin out a bit after hours of use but I can rotate it to a more solid side or just remove it. As long as you've got enough airway to vent exhaust you should be fine. A laptop cooling pad just helps remove the excess exhaust and provide a cool stream of air for the CPU or GPU generating the most of the heat.

Yup that's what I have a 4 yr old HP DV5Z with AMD chip. It runs hot. The newer Hp and maybe even the Lenovo probably runs cooler but it's not a bad idea to keep hardware cool as heat kills many tech items. Probably a combination of both killing unnecessary items and using a cooler would be good choice for him.
