Title: Fan Noise
Review: The fan is improperly balanced and makes a clicking noise at low speeds. At top speed it sounds like a jet engine! It cools 10C better than Intel stock cooler but at approximately the same noise level - my power supply is the loudest fan in the rig when the Zalman is spinning at lower speeds. Astonishingly, it cools my i7 reasonably well as a heatsink without any fan at all. The Zalman website is terrible to navigate and very slow. Also - this cooler requires patience and nerve to install, the instructions are pitiful. I would like to replace the fan with one that is not defective - if I can do it without having to take the heatsink off the MOBO first. No way I have found to contact Zalman about that. Be aware that if you want to install this cooler, you should plan to install it while the MOBO is outside of the case. It is very heavy.
