1.15v is perfectly safe but I would monitor whether this fluctuates when your CPU is under load. CPUz is pretty good to monitor this in real-time.

70c is OK for FSX just dont run IBT or Prime.

If FSX plays well then that's the only real test that matters, don't worry about the heat anymore go enjoy flying!

 Don't have to tell me twice!! 

 

Thanks turboken

The problem with this advice is that if we are talking about a reported CPU temperature of 70c the actual core temperatures will be higher, possibly 20c+ higher which would not be OK. Unfortunately as far as I can see the OP has yet to confirm what his core temperatures are when under load. 

 

The reason why stress tests such as Prime or AIDA64 are used is to check the stability of an overclocked system and to make sure that the CPU cooler is up to the job. FSX only utilises a single core at 100% so will not heat the CPU as much as other more CPU intensive software / games so it is not a good indicator of system stability, and above average temps when running FSX could be indicative of a cooling issue.

 

I personally think that it is important for the OP to stress test his machine for a couple of reasons. Firstly the closed loop water cooler he is using may have developed a fault leading to the higher than expected temperatures which lead him to post here, which if left unchecked could have expensive consequences. Stress testing will help confirm whether or not the cooler is not performing as it should or if it needs attention. Secondly he has made adjustments to the way that power is supplied to his CPU, after such a change it is important to confirm through stress testing that system stability including temperatures have not been adversely affected.

I understand your point PieEater. I have stressed tested the computer when I initially overclocked and can re-test this week to see what my temps are full-load are.

 

I will also use RealTemp this week to monitor my temps while playing FSX.

 

When I was re-seating my CPU the other week I did notice that on the radiator for my H100i (which is screwed into the top of my case as an exhaust) - one of the fans was very partially covered by the back of the case and not exposed to the vents at the top.

 

Like I said earlier, at this point I just want to know that my temps are within safe ranges so I don't have to worry about it. I think the next time I build a rig I may try a place that would build and OC it for you (possibly something like Origin). While I did enjoy the experience, I feel now that I spend more time worrying about my handywork building and OCing the machine, than I do actually playing flightsim. Ok, I'll get out of the wambulance now. ^_^  Thanks again for all your help!

Here are my temps according to RealTemp after a 15-20 minute flight in FSX. 

 

Maximum temps:

66C     63C    63C    64C

NP - I believed that you had taken my comments on board I just wasn't too happy with some advice given to you and potentially others that may stumble across this thread in the future and wanted to qualify where I was coming from. 

 

I have just done a quick 15 minute flight any my temps are similar to yours - 61 / 64 / 69 / 65 - although we're not comparing apples with apples when it comes to CPU cooling solutions (closed lop vs air) I don't recon you have anything to worry about as long as your cooler isn't struggling to keep things under control.

Thank you very much PieEater. 

 

I appreciate everyone's efforts to help answer my question and reassure my worries!
