Its been a while since we have heard of passive cooled graphics cards. Its almost impossible to make an AMD Radeon GPU with a passive cooler with out risking a massive fire. NVIDIA on the other hand has managed to develop GPUs which are not only power efficient but also run much cooler than its competition. Palit KalmX series graphics cards are equipped with Maxwell architecture thus making them the ideal choice for passive coolers. Palit KalmX series makes its mark with GeForce GTX 750 and GTX 750 Ti.
Palit KalmX Passive Cooler for GPUs
Palit KalmX GPUs will feature a passive cooler equipped with a copper base and two nickel plated heat pipes passing through a large aluminum fin stack. NVIDIA’s Maxwell architecture is so power efficient that both GPUs do not require additional PCIe power connectors instead use the on board 75 w power supplied by the PCIe slot.
Palit did not decrease any core clocks on the GPUs due to the passive cooler. The GeForce GTX 750 Ti KalmX features 640 CUDA cores clocked at 1020 MHz with GPU Boost 2.0 up to 1085 MHz. It features 2 GB GDDR5 memory spread across a 128-bit memory interface clocked at 5400 MHz respectively. The max TDP of the GPU is just 65 W and absolute zero noise pollution thanks to Palit KalmX passive cooler.
Palit’s GeForce GTX 750 KalmX is not much different except for its 512 CUDA cores instead of 640 and 5.01 GHz memory clock instead of 5.4 GHz on GTX 750 Ti. GeForce GTX 750 comes with a max TDP of just 55 W. In terms of display outputs, both GPUs include two DVI ports and a mini-HDMI port.
