Hi i've installed the new noctua heatsink and the problem remains unfortunately. So the H80i wasn't causing the restarts. Although now I do have cooler cpu temperatures at idle which stay around 35-40 degreesC which I think was due to the hot coolant inside as you mentioned thanks :) I think the restart problem lies with the motherboard and could be anything from a loose capacitor, to a bios that needs flashing. I have tried a lot of removing parts to locate the cause of the restarts after 5 seconds before any screen output, but no luck so far still. If I do buy a new motherboard I may aswell go all out and get a new cpu, ram and basically new computer. But thats a lot to spend on a computer that once it does turn on, it stays on fine all day with no issues.

Hi thanks for your thoughts :) Yes that coolant appears warm! and may have got warmer overtime (I haven't noticed temp increases much to do with the cpu). *This winter feels mild in the UK compared to prior years thats for sure so far. The air out of the radiator is warm and both pipes at an equal warmth when the pc is running so it appears to operate ok. (once the bootloop restarts have occurred each day) I went for an air cooler this time ::pirate:: and ordered a new noctua D15 which is massive. And until thats in i'm still not entirely sure (but am preying) that the corsair cooler is the issue... Unfortunately i don't have a spare 1150 board to try it on. The 850w bequiet psu I feel is pretty under utilised with my system, Temps right now after remounting the cpu to the H80i are around 5 deg hotter and idle at 45degC with the arctic silver 5 which was expected Ah its corsair link 2.7 yep quite silvery

The ambient room temperature is 20 degrees C. This is how i have the corsair link setup. Occasionally i increase the fan speeds or slow them down in the summer slightly. Does anyone know if there is a way to flash the H80i so it would be back to factory defaults or another firmware? %5Bimg%5Dhttps%3A//i.imgur.com/xNoroJw.png[/img] Thanks, Jake

Hi over most of this year my pc will start and after about 5 seconds restart, in a loop for at least 3-4 times before finally booting. No input on the screen when it restarts. Occasionally it passes bios post and just before boot menu select it will cut out and restart then. It was quite random and used to boot fine for several days before the restart loops occured. But lately its every single turn on I have a corsair H80i and an overclocked 4690k cpu. [ame= ] [/ame] I am considering buying a new H80i to replace the current one which was bought in December 2014. -- -- Is a replacement worth thinking about, or do these coolers have lifetime warranty? I have uploaded a video today to show what happened when I took it out of the computer case. I have tested the psu with the paperclip method and plugged in a fan and it had no restart issues. I have tried new bios batteries, disabling the overclock completely. Checking stand offs on motherboard, plugging and unplugging the CPU Fan cable, unplugging h80i fans. Memtest with ram for 4 passes over 2-3 hours with no errors. Issue remains with no ram installed. And today reseated the cpu with new arctic silver 5 compound and the restarts continue. I think that the back plate of the h80i is touching the metal of the case behind the motherboard. I considered putting some masking tape over the metal backplate but haven't yet. Also when I took it out in the video it wouldn't of shorted at all on cardboard but the reboot cycle occurred. I am only guessing that a pc outside of the case with nothing connected to it should stay on permanently as i've not tested it outside like that before. Do you know if corsairs warranty is lifetime, and also do you think a new corsair h80i might do the same on my system. I am preying to get the system to turn on first time fine all the time Thanks for reading, Jake
