3. Nofan CR-80EH

Design

The Nolan CR-80EH is a bucket-shaped CPU cooler with a distinctive design.  The CPU cooler is copper and has many ICE pipes or extremely thin heat pipes.  The goal is to have a greater surface area and dissipate as much heat as possible into the environment.  The Nolan CR-80EH fanless CPU cooler is compatible with nearly all major CPU sockets and supports CPUs with a TDP of up to 80W.

Shape

The CR-80EH is smaller in every way, with less than half the heat dissipation area and a basket-like shape that is broader at the top than at the bottom.  The principles of both devices are the same, with a huge base, a set of copper wires that make up the majority of the heatsink, and a single heat pipe connecting the two systems.  Intel LGA 1150/1151/1155/1156 CPU sockets are supported by AMD AM4/AM3+/AM3/AM2+/AM2/FM1/FM2/FM2+ CPU sockets.  No, there are no heat pipes (ICE Pipes).  CPU TDP Compatibility80W maximum155mm Cooler Width113mm Cooler Height

Considerations for Compatibility

When picking a motherboard, extra consideration must be given to the size of the cooler.  While it will physically fit on all compatible boards, the motherboard (with the cooler mounted) may not fit in an appropriate case due to the location of the CPU socket.  If the CPU socket is too close to the motherboard’s edge, this can happen.  Measurements should be done with the motherboard already installed in the case to confirm that there is no obstruction within a 92mm radius of the CPU socket.  Nofan has compiled a comprehensive list of all known CR-80EH compatible motherboards.

Verdict

The construction quality may be improved.  Also, unless you have excellent ventilation, expect to use a case fan under stress and don’t bother with high-wattage CPUs.

Conclusion 

A Best Fanless CPU cooler does not often seem radically different from a standard fanned PC, especially compact form factor fanned PCs.  Nonetheless, there are a few subtle mechanisms in place to keep these quiet, unassuming pieces of technology from catching fire.  So, how can a PC with no fans stay cool?  Fanless computers are frequently cooled by the conduction principle, which involves something heated, releasing heat into its surroundings through direct touch. 

Although heat conduction is a natural occurrence, the amount of heat dissipated can be changed greatly by design.  The basic concept is to connect heat-generating components, such as the computer’s CPU, to a heat sink.  A heat sink allows the heat generated by the components to pass through it and into the atmosphere.  It’s critical to think about what materials you’ll use and how all parts will interact when constructing a heat sink assembly.
