Other fans that I ordered still caused a "fan alarm". Worked with your tech support who recommended the MECHATRONICS G6015M12B2-RH replacement fan. The fan comes with flying leads, so I just cut the connector off of the old fan and spliced it onto the new fan. This is a good replacement for the original fan a Nonoise G60115S12C2 fan in a Samsung OS7100 telephone system Works great. Quick, low cost shipping. Thanks for the help Cooler Guys!
