Do laptop cooling pads work or are they just propaganda?

A laptop getting hot while gaming is expected.

Laptop cooling pads work as well as shoving a tiny rectangle object under the back of it lifting it off of the table.

 

The goal is to get more air here into the system with less resistance. Making the distance between a solid surface and the vents bigger is how to do so.

 

Any active fans or any of that provide NO BENEFIT AT ALL. The fans in the laptop do the cooling these other fans just waste electricity as they can't force more air into the device in any way. What can happen is that when the fans are off in a laptop and the cooling pad fans are DIRECTLY blowing into the cooling holes you end up with accidental airflow in the laptop and some bonus cooling at idle.

 

The only time this can help a teeny tiny bit is with laptops that use the chassis to cool themselves but those are basically non existant as that is technically a health hazard if they use the bottom panel.

 

But largely just lift the butt up from the laptop and well thats all you need.

Fwiw, my dad's work laptop(HP EliteBook something) I think got ridiculously hot while he worked and used to crash. I was skeptical of a cooling pad, but he ended up buying one and the laptop didn't crash again.
I have no idea why the laptop didnt throttle and just outright crashed.

I am getting pretty fucking sick and tired of the "watch something else" responses. It's such a cop out answer because you could say that about basically anything, and it doesn't address the actual complaints. People use it as some kind of card they pull when they can't actually respond to the criticism raised but they still feel like they need to defend some company/person. If you don't like this thread then stop reading it. See how stupid it is? It's basically like telling someone "shut the fuck up". It's not a clever responsive, it doesn't address anything said, and it is rude.

MKBHD is but an Apple propagandist and fanboy. Take his videos with a grain of salt, especially about anything Apple. In his video titled "I Visited Apple's Secret iPhone Testing Labs!", he has shown that he makes no effort to fact check Apple's claims, and takes it at face value. I do not believe he can be trusted as an Reviewer/Influencer.

the keyboard was getting too hot to touch

Yeah, they do that.  Instead of getting a fan-based cooling pad, think about getting one of those metal laptop stands that are very well-ventilated from the bottom, lift your laptop off the ground, allow for increased airflow.

 

But in reality, any laptop is going to get warm while gaming. One using a high-power CPI and a dedicate GPU will get hot.

I enjoy buying junk and sinking more money than it's worth into it to make it less junk.

actually yes, but it depends how well the fans line up with the laptops intakes...

 

on my laptop which gets around 80c without it, its good enough for ~15-20c lower temps enabling me to actually play games which is otherwise impossible because the laptop also starts throttling like hell at like ~70c 😅

... wrong?

 

my cooling pad without the fans on will indeed lower the temps by like 5c... way too little to be of any effect... with fans on tho.... its also really noticeable because the keyboard stays relatively cool with the fans on.

 

 

by the way it was the cheapest cooling pad i could find on amazon... 15 bucks or so lol...

see above... would file that under internet myth tbh, or you didn't make sure the fans did actually align with the intake vents.

very similar experience here too... my laptop didn't crash... but throttling sub 1ghz made it unusable for gaming anyways.

Options include, as stated before:

  • making sure that there is a significant space between the laptop and any barriers, and a flat surface or, even worse,  your lap, a pillow, a blanket, or anything else that will block the vents, especially crazy ants! 😉
  • A laptop stand that has fans that match both the position and direction of flow of your hot box...errr... error... fans. Despite the denials of others, I, too, have trapped the benefits of a stand although at that time I got lucky in choosing one that worked well with my overheating HP a decade or so ago. 
  • Get a Frore Systems AirJet and mod your laptop with it.
  • Do what Kris showed. 
  • Get a better computer (desktop) and use the laptop for things that aren't heavy load. 

If none of those options are appealing, let us know. 

I've been using computers since around 1978, started learning programming in 1980 on Apple IIs, started learning about hardware in 1990, ran a BBS from 1990-95, built my first Windows PC around 2000, taught myself malware removal starting in 2005 (also learned on Bleeping Computer), learned web dev starting in 2017, and I think I can fill a thimble with all that knowledge. 😉 I'm not an expert, which is why I keep investigating the answers that others give to try and improve my knowledge, so feel free to double-check the advice I give.
