Proper cooling systems are arguably the most important part of a fast-running, interruption-free computer. Without adequate cooling, workstations can overheat causing CPU slowdowns and system freezes translating into downtime. Fans like the FAN478 offer great cooling at a great price. Suited for Pentium 4 environments, this super-duty Socket 478 CPU cooler keeps your computer running at optimal temperatures. The closely spaced fins of the aluminum heatsink provide increased heat dissipation; more effective than normal heatsink/fan combos.
