Laptop Vacuum Air Extracting Cooling Fan-is it good?

[Whitebeard1]

I was looking for some cooling accessroies to cool my laptop down(cooling pad, external fan etc.), and I came across a Vaccum Air Extracting Fan. The picture shows that you put it on the outside and it extracts the air out to help cool the laptop. They are relatively cheap, from $5-$20, but are they good and how does it work? Thanks!

The cooling pads are actually like a helping hand to the internal laptop fan. It is of no use if internal laptop fan is not functioning or the vents are blocked with dust because of which the heated air is not coming out of the laptop. I have not used this vacuum fan as you have shown in the pic.
If you have over-heating problems, I would suggest you should rather first check the internal fan, make it dust free and check thermal compound before spending on these stuff.

I really don't see the point of these sorts of "add on" coolers for laptops.  When a laptop is built its internal cooling system will be capable of cooling the laptop fine, so if down the line it starts overheating and needing extra cooling, you really should get the internal cooling system checked (It's probably just dirty and needs cleaned).

To me the logic of "Oh your laptop is overheating, get this external cooling device" is flawed and seems similar to "Oh your roof is leaking, put a bucket under it" - You should be fixing the cause of the overheating rather than trying to patch it up.

And if you aren't experiencing overheating then you really don't need to do anything to "cool your laptop down" - It should be able to do that fine by itself.

I completely agree to Camerongray.

Hello, thanks for the replies, they were helpful. I cleaned the fan with compressed air as shown on some tutorials. There was a little bit of dust there, but not too much. After the fan has been cleaned, the computer still overheats. When I touch it, it is very hot. Speedfan also said it's overheating. Anything else I can try, besides the external fans?
Thanks very much.

Its a laptop, if you blow air without taking it apart, you may see some dust coming out. But the solid dust is still inside stuck in the vents and fan. To properly fix this problem, (if you feel confidant), take the laptop apart, clean the fan. Make it completely dust free. If possible use a soft brush to clean the corners. DO NOT WASH and do NOT use a cloth to clean the motherboard or around it. Be very careful while cleaning the fan, the blades are very delicate. Clean the vents so that hot air can freely pass out. If necessary change the thermal compound on the processor. Compound on the GPU may not be required to be replaced.
Do make sure you don't force on 'any' screw while putting it back. Forcing may break the plastic around and / or break the plastic which holds those golden threads.
If you feel it is getting difficult to take apart, better to give it to a shop which can professionally do it.

Hello. I took it to my local computer store, and they took it apart and had it cleaned for me. Thought they fixed the overheat problem...nope. The laptop looked fine whe it started up, but soon the temperature will be at around 60*C. 
Thanks,

Hello. I took it to my local computer store, and they took it apart and had it cleaned for me.

Did they replace the heat sink compound? Did they check fans are working fine?

What laptop is this ? ?...60c may be just about right for it.

[Whitebeard1]

It is a Asus laptop. Also PCdoc, I might take my laptop to that shop again to get these things checked.
Thanks

When you say "overheating" do you mean the laptop is actually throwing up warnings? Or it's just uncomfortably hot? As I recall, the "MAX TEMP" is speedfan is a custom number which defaults to 50 or 60C... Your CPU's max temp may be much higher than that.

Also, Asus laptops tend to have some of the best cooling systems for laptops (from what I hear and personal experience)... so I doubt it's actually overheating unless you're using it on a surface which doesn't allow air flow (i.e. resting on a: pillow, blanket, towel etc.)... If you provide your exact model we could advise you better...

P.S.
   +1 to camerongray... an add-on doesn't fix the problem.

It is a Asus laptop.

 They make quite a few different ones...

Do you hear your fan speed revving up when the laptop is under heavy tasking?  Do you ever look in Task Manager to see whether any particular program is persistently consuming CPU resources?

@camerongray My system reaches 100 degrees on the GPU and 90 on the CPU with full load. The CPU is intel i5 6200u and GPU AMD R7 M370. Its a ThinkPad and the Heatsink+Fan system has been replaced by Lenovo today and the temperature does stay the same. I don't know much about the overengineering part of these systems, but if a thinkpad is reaching such high temps laying on a flat table all the time then there is some need for a extra cooler to stop it from dying.

100 degrees Fahrenheit or Celsius?

if it's 100C then it should be dead already.
if 100F than that's only 38C and is well within normal range.

what software are you getting the temp from?
if Speccy, double check with another software as Speccy has been known to sometimes report wrong temps.

Not sure if anyone noticed but the Topic is 4 years old +...

[Mark.]

yep, noticed that, but the OP wouldn't care anymore. that rig is long gone. 
plus swapnil directed it at camerongray and it's for a new issue so thought thread hijacking wasn't an issue.

I don't think that vacuum cooling fan a good ide to use it.
You can read the artcile about cooling systems at https://gadgets-reviews.com/review/181-how-to-cool-a-gaming-pc-selecting-a-cooling-system.html, so they are provide some things about cooling systems.
As for me, i don't use the vacuum system.
