Cutting Out Rear Fan Grill... HELP

post #1 of 10
Thread Starter 
I have a Lian-Li Lancool PC-K62 case and have a pretty thick rear/exhaust fan grill. I heard that it helps to cut this out. So now I need your help, how do I do this?

I know I have a dremel and can easily get tin snips/metal cutters . Which would be best to use?

Do I have to remove all my components from the inside (mobo, psu)?

Will this drop the temps on my cpu at all? (is it worth doing it?)

use the dremel with reinforced cutting disks made for metal.

Make sure to remove ALL components from the case first

cutting the honeycomb will simply improve the airflow out the back. Not sure if you'll really see a drop in CPU temp.

Well I have the H50 Radiator in the rear fan, so that's why I think the CPU temps will go down a bit....

You'll have better airflow, so it's entirely possible to see a degree or two of a drop I suppose. Make sure to add a second fan if you haven't already - that'll help your temps too.

no problem. I set my buddies computer up the same way in the same case with cooler. If you are having temp problems or are concerned about them, then I would suggest re-seating the cooler more than doing a mod.

I am not sure if you have already cut it out yet or not, but I always cut my rear and front grilles (if covered by faceplate) out with a trusty Hole Saw. Usually if they have some sort of honeycomb grill then luckily there is usually one center Hex that the hole saw's guide bit goes into and it gives you a perfect cut.

Bingo! That's how I do it. Make sure you buy a "Bi-metal" Hole Saw.
this is a good Tut

The problem with hole saws is the price. A good Bi-Metal hole saw can cost you $35 USD. Just fire up your Dremel and give it a go.

This is true but, I feel like it was a good investment. I have used mine a few times and plan on using it until the teeth are gone.

Regardless of what you do to "make the cut" it is a good idea to put some sort of U-channel over the new edge for a clean look and to cover the sharp edge.

If you want to paint it, you can just smooth it out with the dremel. Then you'll need to get, "all up in your case with paint."eek.gif

Other uses of a hole saw are:
-cutting wire holes in your desk
-making small speaker boxes
-smaller sizes are good for making wire holes in your motherboard tray
- 4" is perfect for making a hole in your mobo tray where the cpu heat sink bracket is, for easy access to change out your CPU cooler
-and more:rolleyes:

Some cons of a dremel for this application are:
-Will use up many cutting disks
-Sparks
-difficult to make round cuts
-Will put a lot of miles on your carbon brushes inside your dremel
-Not the fastest way for sure

@Smasher I was just looking at your mods, Very Nice!
