updated bios now cpu overheats

[Stupidmonkey110]

I updated my bios to the newest version now the reported cpu temps are double what they have been for the last 2 years of stable use. I have confirmed that all system fans and pumps are still running as normal. I have reverted to default motherboard settings and no change. here are the system specs if anyone has any ideas.

 

Asus Sabertooth z87 - new bios is 2103

i5 4670k - back at stock speeds, only used to have a very small OC

16gb RAM

Corsair AX860i psu

780 GTX GPU

Corsair H100i cooler

Corsair 500D case fully loaded with fans

Windows 7 64-bit

What was the reason for the update in the first place?

Check voltages?

Was having issues with a USB device driver and as part of troubleshooting said driver saw that there was a new bios for my motherboard.

 

Check voltage?

PSU voltages are rock stable. core voltages appear to be normal and have always been set to auto on my motherboard.

What temperature monitoring program are you using? Try using Real temp, because after a quick search programs that come with Asus motherboards sometimes incorrectly show temps.

All the temp reporting tools i have tried all report the same temps as the ones the motherboard report in the Bios.

 

I think that the bios changed how the temp probes are read.

 

Should i try flashing back to the old bios?

Go for it. As the saying goes with bios: 

"If it ain't broke, don't fix it"

Ok i reflashed back to bios 1405 and it is still reporting 60C temps in the bios with the motherboard defaults loaded. cpu volage is reported at 1.040V.

 

Something must have borked a temp sensor, only thing that makes sense.

after some more poking about i have noticed that the outlet tube out of the pump on the H100i is definately hotter then i remember it feeling. but the other tube is cool so the water must be flowing. I wonder if maybe i may be having issues with the pump on the cooler. there is no odd noise but the green and blue LED have stopped working. the reported temps from the pump are very close to the reported cpu temps. so strange that things changed so suddenly and at the same time. after loading the CPU does anyone notice if one of the tubes on the H100i is quite a bit hotter then the other?

Have you tried using a different cooler with it?

[Stupidmonkey110]

so gave up last night. this morning i booted up the system and it got to desktop and then shutoff. turned it back on and got a power surge bios error. wondering if something is causing voltage issues that is then causing excessive heat. I will be pulling the whole system apart today and doing a physical inspection and trying the stock cpu cooler to see if any differences.

ok, so i put the stock intel cooler back on. at idle temps were low 30's, at load in games mid to high 40's were reported. I am going to call the issue as the corsair H100i. just pure luck i guess that the issue happened at the same time as i was doing a bios update.
