Product: Z400 Workstation
Operating System: Microsoft Windows 10 (64-bit)
Hi, I updated my old bios (3.57 i believe) because i switched from an xeon w3565 to a xeon x5690 so my gtx970 doesn't get bottlenecked.
Now my GPU stands at 60°-70°C while doing nothing.
It is also possible that just getting a better power supply would fix this since i am pretty much at my psu limit 475W..
But i want to try to downgrade my bios to older versions to see if the problems exists mainly because of the bios version.
How do I do that? When i try to select older versions via F10 Usb flash it says they are not valid (because they are older)
Thanks a lot for your help!!
Edit: When i play some games the GPU only like 55°C hot... so its the psu?

In my opinion doing a bios downgrade will have no effect on your video card temperatures and trying to do so risks the system becoming a brick as a forced downgrade of the bios is full of risks
the xeon w3565 is a130 W part, the xeon x5690 is the same wattage, but has 2 more cores
some z400 systems came with the high performance cooler and some did not check which one you have the preferred one has 3 heatpipes
the stock 970 is factory rated for up to 98c and is a 145 watt part the fans do not kick in until the temp is over 60c my idle temp was around 56c-58c until i replaced the stock cooling with a aftermarket kit
if you want lower cpu/gpu temps check the system airflow, the card fan/heatsink, run a app to control the video card fan curve, increase the z400 default bios fan setting or replace the video cards current cooler/fan setup with a aftermarket setup
or water cool it (this kit requires a pump also see picts)

The Z400 version 2 with a high end processor (now inexpensive) still has life left in it. Agree with DGroves that downgrading BIOS is not the way to go. You must have the later better version 2 Z400 to be running the X5690, which is what I used on all of the Z400 upgrades I have done. However do double check on the heatsink/fan you put over that upgraded processor. If you started with the "mainstream" rather than the "performance" heatsink/fan you have a problem that you need to fix. Luckily the performance heatsink/fan units are inexpensive due to the large number available.
Here's some added hardware information. I'd put priority on adding a front "PCI" intake fan/card guide and the air flow guide posted about HERE . I've done both in all the Z400 souped up builds from the past.
The vast majority of Z400 workstations came with the higher cooling capacity larger heatsink/fan. Read up on that in the link... I also added on a northbridge fan to the finned heatsink already present (there is a 4-pin spare motherboard header for that conventional PWM fan). Plus, added a HP "2x2" PCIe Texas Instruments chipset USB3 card as posted about here. Nice project workstation, typing on one right now.
