I would suggest using Gigabytes own software to check the temperatures, it could be more accurate than other software since it's from the mobo vendor, I highly doubt that the temperatures are actually that high.

Changing to better CPU coolers/water cooling definitely wouldn't help, stock coolers blows air towards the board and thus the VRM can somewhat get some airflow to cool it down, while with tower coolers or water cooling there is almost no airflow at the VRM so the temperature gets higher, this is my own experience. Some cheap heatsink should help cool your VRM down.
Same exact results with Gigabyte SIV...

Most of the VRM sensors on these boards, especially lower end ones are bogus.

This board lacks any form of VRM cooling whatsoever. I'd imagine they easily get into high 80s with more demanding games. As @FreedomEclipse said, the only solution would be to attach small aftermarket heatsinks using thermal epoxy or double sided thermal tape. Even with those, I would still add a fan blowing directly onto the VRMs.
Alternatively, you could have a fan blowing at the back of the motherboard (CPU socket area) but your case won't support it.

A fan over the VRMs without any heatsinks is fine.

yea i'd like to have a temp gun

btw this is the sensor type if that means anything i don't know anything about boards sensors: ITE IT8686E (ISA A40h)

IT8686E is just LPCIO controller, it does all kinds of motherboard housekeeping from sensor monitoring to legacy port support. The sensor itself would be ether a small transistor or diode near the VRM MOSFET, or even using the MOSFET's body diode itself as sensor. The former usually gives you case temperature, the latter gives junction temperature.

I'm not sure if the displayed temperature is junction temperature or case temperature. 124C junction temperature is kind of normal. "Kind of" since while that's normal for industrial devices, it's quite unusual for consumer products. 124C case temperature on the other hand would make me very worried.

Anyway, the best way to cool VRM MOSFET is to cool the PCB. Adding heatsinks on top of the MOSFET itself won't help much, if at all. Just look at typical MOSFET case thermal resistance as to why it won't be effective:

Just hang a fans over the vrms. If you're really that worried get those little aluminium heatsinks with thermal adhesive pads and plop them on, and a fan.

Well as far as i'm concerned my stock cooler is blowing air at the VRMs + there is room for only 1 more 120mm exhaust in my case, i don't think that'll make any difference.
Hi,
Even a stock heatsink vrm's should follow the cpu temp on temps.
So I'd say you have an issue.
