that sort'a sucks, should be at like 4.5+, i know ivy is supposed to run hot but didn't think that hot. you can get a 2600k at 4.2 or 4.3 all day long with good temps with a 30 buck cooler.
Could possibly be the fact that you're using such a small board. They were never the best for overclocking. Looks like Salvage is using a 3570K with a UD5H, the UD5H should have more power phases than your little board, so it will be better for overclocking. I think 4.2 is fine for a little board like that.
I think the problem is in the cooling. He is at 1.23v that should be nothing for a custom liquid system.
What voltages were you using for 4.6?
Could be some issue with the cooling but I think the board could be partly to blame too perhaps. Could it be a possibility?
You see, I still had no time to attend to the overclock myself, so I decided to try out the asus's auto overclock software. The voltage seems to be set to 1.232V. Plus I don't think that the cooling is to blame. Even at 4,23 GHz and with overclocked GTX 670 I get 66 degrees on the CPU and 45 degrees on the GPU, all under 100% load simultaneously.
The way I understand it the big part that the motherboard has in cpu overclocking and temperatures is how the power is being delivered to the cpu. Boards that are not as good at delivering the power might need higher voltages in order to over compensate for the power not being as reliable as other boards.
This board is really good for an ITX board. The 10 phase power design that it has is definitely in the range or being able to provide power to the cpu for a good OC. So far the limiting factors for the OC is the temps not the voltages as far as I can tell. That might have something to do with mr. doom using the auto OC features.
The reason that I am thinking that there is something wrong is that I doubt that the auto OC is using much more than 1.4v for 4.6GHz. Which should be way overkill for that speed. If I remember correctly I was getting upper 80s and breaking into the 90s when stress testing at 4.9GHz with 1.5v. comparing the cooling you have twice the radiators that I do, they are better rads to begin with. A better cpu block with more water flow from a better pump and larger tubing. Now I understand that you have a GPU on the loop as well but the temps still doesn't add up to me.
Take a look at this guide. I used it when I first OCed my chip. It will have the basics as well as some good pointers if you want to really tweak your OC.

Nice mini watercooled pc you got there! Some parts you could have cheaper though ;P
Looks great with the blue leds behind the can.
Thanks! Those are white leds, liquid itself is blue
I thought so
How cool is it? Can you post some results?
