Cheers. Ill take a look. Im going to try removing the gpus as well to rule out psu issues. The reason being sometimes when i boot the fans require me to turn up to 100% before they start spinning, only then can i turn them back down to 65%. Unless of course im being noobie and im doing something wrong. Seems odd that they dont like starting at the set speed on my controller. Its not all the time though.
