Thermaltake NiC (Non-Interference Cooler) Series C4 CPU Cooler Review

At stock we can see some very impressive numbers from the NiC C4 performing right up there with some other premium air heatsinks.

Due to these fans running via 3 pin connections with a manual fan control knob, we decided to test at minimum fan speed, which was still a quite high 1000RPM. As you can see at 1000RPM the NiC C4 isn’t the quietest option but the noise levels are still pleasant.

Overclocking saw some very impressive numbers. At minimum fan speed we saw impressive results putting this CPU cooler in contention as one of the best air coolers we’ve tested. What surprised me was just how much better the NiC C4 was compared to the NiC F4, yet the only difference it has is a nickel plated base, more powerful fans and an extra 5mm in heatsink height.

Again default acoustics at minimum fan speed were pleasant compared to the competition. With maximum fan speed the noise levels were very piercing, but at 2000 RPM you’d expect that. All in all the acoustic performance from the NiC C4 was adequate, but there are definitely much quieter CPU coolers on the market. The fact the fans start at 1000 RPM, not 800 or 600RPM for example, mean this CPU cooler is a lot louder at idle. Inside a case though you would be hard pressed to notice it over the general hum of a system.
