midniteboss Posted September 21, 2012 Share Posted September 21, 2012 Since last month, I've been using my H100 on my i7 3770k with a 4.5 ghz and its been running fine. Temperatures would never go over 75 after 5-6 hours of running prime95. But when I turned on my computer today and checked my temperatures, I noticed that my idle temperatures were a bit too high on idle. Usually they sit at around 18-25 degrees Celsius but today this time they were sitting at around 35-42 degrees. I checked all my cables and they were fine because I haven't even touched the thing in a month since I installed it and immediately overclocked it. I decided to run prime95 and immediately my temperatures hit TJ Max and my system shut off. I cleared my cmos and went back into windows and checked my temperatures again. Surprisingly they were still the same at idle. So I decided to run prime95 once again and after 20 seconds, my temperatures reached 100 degrees so I exited prime quickly before I hit TJ Max again. I turned off my system and uninstalled the h100 and checked the thermal paste and it was fine. I even tried reapplying a new set of thermal paste but it didn't solve the problem. So I took the H100 out of my system and installed the intel heat sink. When I turned on my computer to check temperatures, it was idling at around 24-30c which is really good for the intel heat sink. I even ran prime95 and the highest temperatures it reached was 60-65 which is completely normal for the intel heat sink and I think that's even considered low in some cases as well. So there is definitely a problem with the H100. Im thinking that I just got unlucky. I still have my receipt and the box that it came with so what can I do now? Will you guys be able to replace the H100 with a new one if I ship it out to you? It was purchased on the 17th of August. Thanks Link to comment Share on other sites More sharing options...
Toasted Posted September 21, 2012 Share Posted September 21, 2012 Check the molex connection and the pump's RPM in the BIOS. The 3-pin header should be plugged into the CPU_FAN header. If it is, The BIOS should read the CPU_FAN RPM around 2000-2200RPM. If it is under 2000RPM, request an RMA to replace the H100. Yes, Corsair will send you a new unit to replace your faulty one. If you need your H100 quickly, call customer service by phone and ask for a Advanced RMA. If you are outside US, You can use Skype to call Corsair's toll-free number.
