ptop cooler with fan(s) work for the np8268s?

Hi,

Expecting my new np8268s in two weeks. I know this unit had a dual-fan setup (one for cpu and one for gpu), but in case this is insufficient to cool the laptop during max loads, i will be buying a laptop cooler.

If i would use one, should i have the cooler fans:

A) blow air directly into the intake vents, or
B) blow air to the exterior panel?

Do the onboard fans of the laptop actually suck in air from outside or do they just blow the hot air (present in the interior spaces during heavy load) out back the exhaust vents? I'm thinking if those fans need the extra help to draw in cool air from outside?

Any ideas would be appreciated, but i especially want the opinion of those who actually own coolers. Thank you!

 

I've owned multiple coolers over the years, I even modded a CM U3 with a Silverstone 180mm penetrator desktop fan directly blowing on to the heatpipes.
I can tell you now, don't expect too much, the primary purpose of a cooling pad is to ensure the laptop gets a steady supply of ambient air at all times, it doesn't actually augment the laptops cooling all that much directly. That 180mm modded cooler of mine? It was pushing 160cfm of air with extremely high air pressure and my temperatures only dropped by 5 degrees.

 

The Thermaltake Massive 14 Squared or Thermaltake Massive 14² (Both the same thing) are the best coolers available for laptops of that size. They work astonishingly well, and dissipate heat very quickly. If you can't get one of those, get the Coolermaster Notepal U3, or the Deepcool Multicore x6. These two are also great and have movable fans.

As for the laptop fan, it blows air all through the exhaust. This is where the cooler comes in as it blows air through the vents thus cooling the laptop,

 

This, most benefit from coolers is the simple elevation they provide, this reduces the air resistance to the fan pulling in air.

Unless you are blowing chilled air in extra airflow will make little difference.

 

So these "xxx cfm fans" are actually a marketing gimmick then?

If that's the case why do people invest in these when probably a simple stand with a mesh-like bottom to seat the laptop would work just as well?

I've read reviews of people who actually tested coolers before buying them, and some did mention that certain models produced differences of up to 10 degrees C in the same laptop. Your thoughts please?

 

Welllll.... the answer to that would be... 'it depends'.

Overall, yes, it's a bit of a gimmic, but in some laptops the cooling is fairly significant.

Here's the reason why.

The airflow itself isn't really increased, per say, and it doesn't really cool it off by blowing more air, per say.

The difference it makes is the air pressure.

The higher the air pressure in a laptop case, the smoother the air flow to all the components inside that chassis.

Most fans in a laptop, while they can drive a fairly significant amount of air, especially the clevos, the issue is with all the bends, components, blocks, etc, the air flow may not be consistent throughout the entire chassis.

The laptop fans push a higher overall air pressure into the chassis, thus, allowing a smoother flow of air to all the components, and that will actually show a lower cooling as air is finally able to get to areas faster and in a more equal manner than it may have been able to get to previously.

That's the only real buy in with laptop coolers, and for those cases, the cooling could be significant.

 

Hello I recently got my 8268. I use a Targus travel cooler. Targus Space Saving Lap Chill Mat AWE80US - Newegg.com I found this much cheaper elsewhere.

I actually use my laptop on my lap and wanted some cushion. This was what I used when I was overclocking my under powered aspire 5560G, for years. I needed something comfortable for the multi-hour gaming sessions. It fits great in my backpack with everything else I take with me.

 

Targus is a fine brand for peripherals and i like the form factor of this product, but IIRC the Chill Mat has only one massive fan. I don't know if this is more efficient than having two cooler fans that are more or less directly under the air intake vents of the np8268. I'm leaning more toward that Deepcool Multicore X6 (a bit silly-looking but, hey - it has got 4 fans!) which somebody up mentioned.

But if you can state, from your experience using it, that your Chill Mat actually does make a 10-12 degrees C difference in laptop temperatures...then I'll probably consider that Targus too. :thumbsup:

 

Well dude, I guess that's a roundabout way of saying "laptop coolers DO work", although from where i sit i think you ned to factor in several conditions like airflow available where you located your laptop, maybe ambient temperature also, and pretty much how good your laptop's cooling system is.

Considering that i will mostly play in my living room (which is not airconditioned) with ambient C's in the 80s, maybe I do need to have a laptop cooler handy.

...unless somebody here who owns a NP8268s and living in a relatively warm climate zone will swear by those dual fans? Sorry if i sound like i'm an old lady here but i'm real titchy when it comes to temps. Want my investment to last quite a bit (and i've got really sensitive fingers to heat), you understand.

 

With most clevo's however than fan is sealed against the casing meaning it only draws air from the outside and is not pulling it through the case.

 

I'm assuming you mean ambient temperature in the 80 faerenheight and not celcius?

Unless you live in an active volcano

I went to a friends house who had 82f room temperatures. The fans did kick up but it should be noted that the fans never kicked to max.

Playing borderland 2 for 6 hours, with it laying flat (not elevated) without a laptop cooler got my thermals as:
GPU: 91c peak, 85c average
CPU: 82c peak 78c average

So honestly you don't need a laptop cooler, as the clevo can cool it well enough, but it wouldn't hurt to have one.

 

Doh! Yeah i meant 80f. :laugh:

That settled it then. "Don't need it, but nice to have just the same." I think I will get one, if only to have max clearance between my tabletop and the toasty undersides of the machine. Mayne something with a nice tilt and not too "gaming" looking? Ashen, what are you using BTW?

 

I have the cooler master u3 cooler. It has 3 placeable fans which are nice since I have one fan blowing in the GPU intake, one blowing in the CPU intake, and one blowing on the copper heatsinks to increase the overall air pressure.

This is the one I got: http://www.amazon.com/Cooler-Master-NotePal-PLUS-Performance/dp/B00ED3WMTC/ref=sr_1_1?s=electronics&ie=UTF8&qid=1409270549&sr=1-1&keywords=cooler+master+u3+plus

 

Yeah, I thought as much. Have to position the fan so that the air comes through the intakes i guess.

The U3 sounds like a mighty fine product, I especially like the fact that its aluminum with no plastic parts (except the fans, that is), and it has a nice utility converting into a sort of carrying case for your laptop (although with the bulk of the np8268s, this might not be feasible -- is it?).

The only problem is, i cant seem to find a store in our location that carries this item. I cant buy from US sellers and have them shipped to my location because its risky.

Have to find an alternative...can i have some thoughts on the Thermaltake Massive?

 

Any stand that props the machine up will do the job, seriously.
