Default Installing 250mm cooling fan in your case

Here is my guide on installing a Thermaltake 250mm cooling fan in your side panel. The case I'm using for this guide is a Lian Li PC-7plus B midtower

Thermaltake 250mm cooling fan from performance-pcs, here

Thermaltake 250mm Silent Case Fan Products Model: TT250FAN [TT250FAN] : Performance-PCs.com, ... sleeve it and they will come

Fan Dimension 250 x 250 x 30 mm
Rated Voltage DC 12V
Fan Speed 600RPM 10%
Airflow 67.69CFM
Noise 15 dBA
4 Pin Molex connector

List of Tools Needed
Power drill
1/4" drill bit
Jigsaw with 18 TPI cutting blade
Dremel or Rotary Tool with 1.5" cutting wheel
Measuring Square or Ruler
Pencil or Pen
3M brand Green Painter's Masking Tape
Center Punch
Phillips Screwdriver
Rounded Hand File
Medium grit sandpaper
"SEM brand Self Etching" Primer
"Plastikote brand Black Enamel paint

List of Supplies Needed

1x 1' x 1' sheets of Honeycomb Modders Mesh

4x #10 x 5/8 self tapping fan screws

4x fan silencing grommets

1x 6ft U-channel (cut down to 27")

Finding placement of the 250mm cooling fan in left side panel. We've positioned the fan 4" from the rear edge and 7" from the bottom edge of the panel.



Trace the outline fan with pencil onto the panel after applying 3M brand Green masking tape.
The masking tape also prevents scratches while cutting the fan hole.



Here is traced outline of Thermaltake 250mm cooling fan. Mark fan mounting holes



Using center punch to mark 1/4" drill holes for fan silencing grommets



Using 1/4" size drill bit to drill holes for fan silencing grommets.



Before we can using Jigsaw to cut the 250mm fan hole, we first make an incision for the Jigsaw blade with Rotary tool using 1.5" cutting wheel



We're using this styrofoam cushion to prop the panel so we have clearance below for using the Jigsaw.



Cutting 250mm fan hole with Jigsaw (use 18 TPI cutting blade)





A sheet of Honeycomb Modders Mesh will provide excellent ventilation





Cut down to 10" x 10" panel to serve as a grill for 250mm fan.



Let's paint the Modders Mesh Black to match our color scheme. First scuff the surface of the mesh with medium grit sandpaper to promote adhesion for the "self etching" primer base coat



After applying SEM brand "self etching" primer, we apply 3 coast of Plasti-kote Black enamel paint



4x Fan silencing grommets ready for installation





fyi: You can use a micro flat head screw driver to help gently pry the grommet into 1/4" hole



Finishing the edge of the 250mm fan hole with U-channel molding cut to 27.5" length



Our 250mm fan hole is finished and ready for installation of the fan!



We prefer to use #10 x 5/8" self tapping screws, these are Black Oxide






First lay down the Modders Mesh sheet (after the Black enamel paint has cured!



You will have to remove a small portion of the mesh around the mounting holes accommodate the #10 x 5/8" screws



The 250mm fan mounts as an Exhaust. It pulls warm air out from inside your computer case.





Now you have a cooler running system with less fan noise than smaller fans!

I've searched high and low and haven't been able to find any. Perhaps a sticky with links to popular stores that sell modding supplies such as hard to find fans, lighting, U-channel, sleeving and what not.

Great guide thanks!

Only one question, if you put a 250mm fan as inlet, doesn't it need the same as outel in term of air pressure/flow thing?

It would add Positive pressure, which pushes the warm out and helps keep your case free of dust.
