Want to use AIO cooling but have some concerns

[justsomeguy1]

I have a Xeon 1246v3 on the stock Intel cooler which I thought would be sufficient but after checking my temps in Speedfan, I found after less than a minute with the CPU going all out, the cores were reaching 100C! What's puzzling is Speedfan said the CPU was around 66-67C which doesn't seem too bad, but if those cores are really at 100C, shouldn't the fan on the cooler be going faster than about 2000? Anyway, worried about keeping my CPU cool I am thinking of using a liquid AIO. I don't want to use air since the only coolers that provide the cooling I would like weigh a lot and are huge. There's no way I can fit a Noctua D15 in there. So my questions are: if I use an AIO what do I do about cooling the mobo? The stock Intel cooler blows downward which helps to cool VRM and such. I do have a 120mm case fan up front and a 120mm in the rear as well, which are not using a fan controller, btw, but seem to flow the air pretty well and not make much noise. I don't know if the airflow they make would be enough to keep the mobo cool.

Another question which may sound kind of stupid: since the pump is on top of the waterblock in the AIO's, wouldn't there be issues with magnetic fields from the motor interfering with the CPU? I also worry about vibrations from the pump sitting on top of the CPU could somehow hurt it. Is that true? If so could I maybe use some kind of rubber dampers on the pump motor? I know I could just build a loop and put the pump somewhere else but I want to go go AIO if I can due to the simplicity.

I wonder if the temperatures you are seeing are correct. I think the computer would have shut down automatically if they were correct.
I have a i7-2600K that shows the same temperatures but has never given me any troubles in years. I think the programs are getting the information from the wrong place or are interpreting the data incorrectly. Even the BIOS setup program on my computer shows those kinds of readings for some reason while the NVidia monitor program shows much lower temperatures.

It's possible Speedfan could just be giving a bad reading. After all, it says the CPU is running about 30C lower than the cores. Even if it's giving bad readings on the cores, 66C it a little too hot for me. Then again this is a Haswell which thanks to Intel cheaping out and using paste on the heatsink, are known to run hot. I would like to get my temps no higher than 60C. For that I'm still thinking water cooling. I like the NZXT Kraken series, particualrly the X31, that would fit just fine
