Hello everyone!
Thanks to some of our pioneers in overclocking and modding the Z620s, here's my progress on the project:
Z620 + 1650 V2 (stable at 4.5 Ghz). Max temp - 49 degrees Celsius.
A few things to mention:
- I wanted a single-processor config, because I need all the PCI ports I can get.
(GPU + NVME + FrontPanel card reader and usb 3.0 + quich charge USB for Android Phone)
- I am shooting for the 1680v2, at the maximum OC it can take (probably 4.8)
- I have quited the Z620 system fans, by replacing them as follows:
1x Arctic F9 PWM (rev2) in the back, hotwired to use the 6-pin from the original double 90cm HP Fans
1x Xilence 120mm fan in the front, 3-pin, replacing the HP original 4-pin - this runs at full RPM all the time, but it's a low-noise, low RPM fan anyway :)
I did this because HP has a custom fan curve for the case fans as well (probably BIOS hardcoded) when the CPU goes into full load.
Also - the fan grille for the Corsair H115i was needed... I have a 3-month old cat running around the house, don't want any accidents :)
