Waterblock design "ROTOR"

Ambient temp now is 28ºC

Mi idle CPU now is 30ºC (Speedfan or mbm)

my cpu go from 30º to 48º in one second when i run torture test in Prime95 and remains for hours

something is wrong? or i have good temps? is normal this variation?

remount the block ! seems you don't have a good contact between with block and the core.

"Waterblock design "ROTOR""
got ne picks of internals of block?

this is the only pic i have.

In my experiences on many forums, the Neo 2 has a driver issue with the temp sensor. DL and flash to the new bios.
That should fix it.

Very true. Even with the new bios readings are still off by a few degrees and they constantly vary. I think they simply cant get it right. My temp probe sometimes shows variations of +/- 11c from what my mobo reports. I wouldn't get too concerned.

sensor really sux

250x10 33idle 49full

no way thats imposible

plz what bios is best for neo2?

I've had best luck with 1.4beta. There was a website where you could d-load pretty much any bios made for Neo2 so far, but I'm afraid the link is dead and MSI forum is currently down. If you want it or wish to try a modded 1.5beta, which is also good, pm me and I'll send it to you.
