Thermaltake has a new series of air CPU Coolers, which they are dubbing NiC. NiC stands for “non-interference cooler”. What that means is these coolers will not interfere with RAM installation in your system. For the longest time many CPU coolers would block your RAM slots or you would be limited to low profile modules. With these new air coolers Thermaltake eliminates that problem. The NiC series is comprised of the F3, F4, C4 and C5 coolers.
