Well i can say for sure the fan that comes with the omen is absolutely horrible.
After installing a Corsair SP120 performance fan, my idle temps dropped to around 24c which is only 1 degree above ambient and after running a 100% CPU torture test, the max temp I saw was 73c with an average across the cores of 66-68c.
Doing a little research into the fan that came with the cooler, I found it is a server fan that is not designed with high static pressure in mind.
HP you are building these computers for enthusiast gamers, you should be putting components in that are designed for their intended use.
I hope this will help any one else out there experiencing high temperatures. I read a few reviews that showed these units running 80c+ on the cpu which is obsurd for a water cooled unit. Replace the rad fan immediately!

I wouldn't think that the Corsair SP120 performance fan would make that much difference. Its high end air flow is not all that great. I did notice that it's a three pin fan and not a PWN fan. All the fans that I use in my custom rig are four pin PWN fans.

Took a temp gun and looked at the thermals around and on the pump and both sit around the 45-50 temp so there may be an error with the thermal reader. As it was consistent across 3 different software suites.
It may also be the heat that is produced off the graphics cards under load affecting the thermal reader. Either way it seems that putting more air across the motherboard and directing airflow out via the graphics card is better for the system than the hot air coming up from the graphics cards and across the rad reducing the cooling efficiency of the water cooling loop.
I suppose this should all be good feedback for HP.
The important thing I would take away from this is that HP should look at the thermal design of the case and the fans they put with the system as changing them had a pretty big impact on the system temp in general.
