where to position fans on laptop cooler?

when i get a laptop cooler with two movable fans, should i put them under the fans in the laptop so it sucks in more air, or should i put them directly over the cpu and gpu? sorry noob question

 

Put under the place, where the air is sucked into the laptop. By this you`ll ensure the intake of cool and fresh air for the cooled elements of the laptop.

 

It doesn't really matter, to be honest.

Your laptop will benefit simply by being elevated, and having unrestricted airflow from the bottom of the unit. Whether the fans blow directly into the air intakes or not doesn't make a significant difference in cooling.

Having said that, it certianly doesn't hurt to have the laptop cooler fans blowing air directly into the air intake on the bottom of the laptop. So if you can manage to rest your laptop on the cooler in such a way that the fans blow into the air intakes, go for it. But if doing so would force you do place your laptop is some kind of weird or unbalanced position, don't worry about it too much.

 

i already elevate it anyways but putting wedges underneath it. thanks though

I put something like these on both sides of my cooling fan, which I need a new one of at the moment.

Gives me the best of 2 worlds, the elevation and air cooling. Also it is very comfortable to be used in bed. I ain't a big fan of desks

 

I have found laptop coolers are more or less useless other than raising the back end to improve airflow. The cooling comes from forcing air directly across the heatpipes at close range. Blowing ambient air around the bottom of the laptop makes little to no difference.

 

not unless u have a great one, that actually works, like my Cryo LX.

i got bored earlier and pulled it out of the closet. i gave it a quick clean with some wipes, and my Dyson, and then plugged it in just to see how the beast was doing. i was instantly reminded why i loved this damn thing so much after just 2 League of Legend games.

1 st game w/o Cryo LX | 2nd game w/ Cryo LX:

-Ambient: 78* | 70*
-CPU: 82* | 73*
77* | 71*
79* | 73*
77* | 67*
-SSD: 42* | 43*
-GPU: 71* | 66*

note that LoL is more CPU-intensive, so that's why that had the biggest temp drops. my Cryo LX is still chugging along after 4-5 years without any hiccups.

 

It seems like a silly question because you're able to re-position or even remove the fans and test the results yourself.

I imagine you'll only have a marginal change if any over just raising the rear of the laptop unless it already has a sub-par cooling ability to start with.

 

Not really. Every laptop I've tested has benefitted a good 2-5C by raising the back end. Giving the airflow an extra 10-15mm in the rear is enough to open up airflow for a decrease in temps. It all depends on the laptop design for sure, but raising the back end is cheap (free) and effective 90% of the time. Laptop coolers on the other hand are added hardware, more noise, consume a USB port, and from my experience marginally useful. There will be exceptions but one shouldn't immediately expect results when using one.
