Laptop Cooler Thread

Hi iunlock,

Interesting, I don't get that at idle L3 OC with the fans in performance mode. The cores were running 22c-23c with the laptop flat on the table (glass tiled top), but only 21c-22c with the back raised about 1.5". I left it for 5 minutes in each case. The fans in performance mode are certainly pulling enough air through, but quite loud!

 

Hmm that's odd. You're ambient temperature must be very cool yea? Also, if you're already on performance mode, I think it'll make less of a difference.

With the laptop cooler, the temps are exactly 10C cooler at idle vs the laptop laying flat on the desk.

 

Hi iunlock,

I think that's about the same as the difference between fans in performance mode or standard mode. I'll give it a try and post the results.

 

For me personally Cool > Silent. I dont mind the noise.

 

Hi DeeX,

Same here! It's like living next to a main road or airport, you get acclimatized to the noise and forget all about it.

 

Thanks, iunlock!

My own testing was running at 100% cpu using handbrake. Much closer to that 10c target.

I'm kinda curious what sort of temps would rsult if the laptop wre tilted but the fans were positioned on the left side and were blowing from left to right under the laptop (or vice versa). To my mind that would do the most work clearing out any warm air while still ventilating the underside, perhaps even better than fans pressed underneath.

 

Did someone tried to replace the stocks 10cfm fans with a 11.7 cfm fan

 

I ended up ordering this laptop cooling pad from Aukey and it is super quiet. Honestly you have to feel the sides to make sure it's on but you definitely feel it.
I repasted my CPU and GPU and that brought down the temps alone to 70 C (CPU was running hot at 81-85 C gaming); now I have them overclocked with settings turned up to ultra on Witcher 3 and Doom, and with this cooler it's still running 68 C.
I'm happy with it. Plus the price is right (had a lightning sale the other day for $24). Just another option for ya.

 

Any new suggestions for a laptop cooler?

for me I use cooler master L3 I believe, a cheap option for me, before that I was using a Modern Warfare Game DVD retail box on back part of laptop.. trust me it helped me get 5C difference, all you need is a little lift on the back side, for me the cooler pad did nothing, may be the particular model I bought is not good enough..

 

Active laptop coolers (the ones with fans) don't typically do a lot. They blow a lot of air at the bottom of the laptop, but unless they're pointing at just the right place, that site isn't doing much.

Laptop's get most of their cooling via fans and heatsinks. The heatsinks are positioned around the back and sides of laptops, and are connected to the hot components with heat pipes. Fans draw air into the laptop, blowing it out past the heatsinks. You're literally blowing the heat out of the laptop via those heatsinks.

You don't get the same effect by blowing site at the bottom of the laptop. Everything is packed in so tightly that there's little room for airflow. If you get any kind of cooling effect, it's going to be minimal.

What a cooling pad does help with is keeping the bottom of the laptop clear. The intake vents for the fans are often on the bottom, and keeping those clear helps more air get pushed past the heatsinks.

Four what it's worth, I've been using a CoolerMaster Notepal U3 for years with my M17x R2. The fans died after a year or so, and the laptop didn't get any hotter than normal. When my AW17 R3 arrives (hopefully next week) I'm going to keep using it. The only thing I'm going to change is to cut some larger holes under the fans, so that they're completely unobstructed.

 

Actually my experience is entirely different. The laptop cooler (Pwr+ 17") that I use on my 17R3 helps a lot.

The difference in temp drop is around 8C, every single time.

I've spent a lot of time collecting data. Yes, I'm OCD. If you look at my threads you'll see, I'm all about show me the money and what's the best, not second best.

When choosing a laptop cooler I wanted something with big holes and with an aluminum surface. Perhaps the combo of both of my criterias has an edge over the cheap plastic ones with small holes?

Laptop coolers work great if you buy one that is worthy and not a cheap toy one.

Numbers don't lie...I'm a firm believer that laptop coolers work in dropping temps.

Mileage may vary for some...

It's quite possible that the design of the AW17 helps. I notice in pictures that it's a lot more open underneath than the M17x R2 is, and that may allow direct cooling off some components.

If you haven't done it yet, I'd be interested to see how much cooling you get using your cooler with the fan turned off. That would validate whether the fan is doing much, or if it's just improved airflow due to the open design of the cooler.

 

Yes the vents of the 17R3 are very good and I believe it is a much better design than the previous generations.

I've done many many tests in an ambient temp controlled environment to obtain accurate data. Below is a screen shot with the laptop cooler OFF and with it ON. The first column indicates the current temp with the cooler OFF. The one in the middle column indicates the temp with the cooler ON.

I've done this test in many different conditions and time and again...it's always ~8-10C cooler.

Hope this helps...



Verdict: Laptop (the proper one) does work. Tested and proven.
