Drilling holes on underside of laptop

post #1 of 9
Thread Starter 
I`m wondering if drilling many tiny holes around 2-3mm diameter in the underside plastic cover of my lenovo would help with airflow/temps?
obviously it would increase dust,but by a significant margin?maybe just under the Cpu and Gpu side?

I`m currently hitting 60-65c at stock clocks in gaming,ambient is around 20-25c I`d say
gpu is also hitting similar temps...

laptop is currently raised by 5-10 degrees with a book
I`m getting a stand with a 200mm fan soon smile.gif

So long as you do this to the laptop cover/shell while it's disassembled and you have no problem taking a serious dive in resale value, i dont see why not.

This laptop will never be sold.ever

I took it apart to redo the TIM so I doubt it`l be much of a hassle

I don't see how drilling holes on the underside will help you. The laptop uses a single fan that draws air in via a vent and exhausts thru another vent.... and somewhere in there is a fin arrangement for the air to move thru to cool cpu/gpu. How would the heat exhaust thru holes drilled in the underside of the case? Heat rises so if anything, drill them in the top and bottom for convection cooling. I'm not trying to dissuade you from cooling your laptop, just trying to be practical and prevent you from doing some unnecessary case mods. Now that might work if you get the laptop cooler with a big fan. Was that the plan to do both? I would try it with the cooler first before drilling anything.

I raise my laptop too, plus I use a cooler pad with dual fans and I have a 120GB SSD. Do you run a SSD with it? The laptop hdd's generate a lot of heat and you can gain some performance and battery life as a side benefit. Good Luck!

Most Lenovos I've seen do not intake air through the bottom, but rather through the side and through the keyboard. I don't think drilling any holes in the bottom would help in any significant capacity- there's kind of a motherboard in the way of air flowing in through the bottom.


You access the fan on Lenovos through the top, not the bottom.

The heat wont exhaust through it,it would be more of an intake since my cooling pad would push air into it.
Nope no SSD,I need capacity and I already have too many externals.
yes the plan is to do both,but I like the idea of trying the pad alone first,I think thats what I`l do before drilling

Mine intakes from the bottom and vents out through the side
and the motherboard isnt blocking the fan

p.s yeah the Hdd really gets hot,sometimes idles higher than my Gpu or Cpu

My cooling bad will blow air up into the laptop from underneath,drilling holes will help with this.
the pad is a coolermaster x3 with a 200mm fan

Exactly!
90 USD means a decent SSD....

Drilling holes is cheap! I know people with a drill and tons of drill bits.
the X3 cooler I`m getting is like 25-30 USD,has 1 USB,200mm Led fan, similar stuff

but my temps aren`t that high
borderlands 2,crysis 2 etc give me 65c for the GPU and 70c for the CPU on average,which seems to be really good for a laptop
idle temps are a bit high... 40c CPU and 35C for the GPU(Probably because of Optimus)
