Understanding PC Parts Part 5: Cases & Cooling

Part 5: Cases and Cooling

PC Case Example

The case houses all your components and determines how cool (temperature-wise) and quiet your PC runs.

A good case makes building easier and keeps everything running properly. Let's keep this simple.

Case Sizes

Cases match motherboard sizes:

  • Mid-Tower (Most Common):
    • Fits: ATX, Micro-ATX, Mini-ITX motherboards
    • Good airflow, easy to build in
    • Fits on/under most desks
    • Best for: Most builds (Our recommendation ↓)
  • Full-Tower (Large):
    • Fits everything, lots of room
    • Heavy, takes up lots of space
    • Best for: Extreme builds, water cooling
  • Mini-ITX (Small):
    • Tiny, portable
    • Harder to build, less airflow
    • Best for: Experienced builders only

Airflow: Why It Matters

Good airflow keeps components cool and extends their lifespan.

Basic airflow principle:

  • Cool air IN from front and bottom
  • Hot air OUT from top and rear
  • Hot air rises naturally

Mesh vs Solid Front Panel:

  • Mesh front: Better airflow (10-15°C cooler!)
  • Solid front: Looks sleek but chokes airflow

For gaming PCs: Always choose mesh front

Important Case Features

Look for these features:

  • ✓ Mesh front panel (better cooling)
  • ✓ Dust filters (keeps components clean)
  • ✓ Cable management space behind motherboard
  • ✓ Room for your GPU length
  • ✓ Enough clearance for CPU cooler height
  • ✓ Easy-access front USB ports

Our Recommendation

For excellent airflow and quality:

Fractal Design Torrent Compact Check Price on Amazon

Why we love it:

  • Outstanding airflow (mesh front)
  • Compact mid-tower size
  • Includes 2x 180mm fans (very quiet!)
  • Easy cable management
  • Great build quality
  • Fits: ATX, Micro-ATX motherboards
  • Price: ~$150-180

This case keeps your components cool while looking great.

CPU Cooling Covered!

We already recommended the perfect CPU cooler in Part 2:

Thermalright Peerless Assassin 120 SE Check Price on Amazon

This handles your CPU cooling needs perfectly. No need for expensive liquid cooling!

Case Fans

The Fractal Torrent Compact includes excellent fans, but if you want to add more:

  • Front: 2-3 intake fans (included with Torrent)
  • Rear: 1 exhaust fan
  • Top: Optional 1-2 exhaust fans

The included fans are great - no need to buy more unless you want extra cooling.

Clearances to Check

Before buying, verify:

GPU Length:

  • RX 7800 XT: ~267mm long
  • Fractal Torrent Compact: Supports up to 420mm
  • ✓ Plenty of room!

CPU Cooler Height:

  • Thermalright Peerless Assassin: 155mm tall
  • Fractal Torrent Compact: Supports up to 188mm
  • ✓ Perfect fit!
