I need the diagram of the motherboard to find out what power is delivered to the plug for powering the fan on the case. I want to connect 2 fans, one original 5w and one 1w. Thanks.

Welcome to our HP User Forum!
Your HP Pavilion Gaming Desktop PC TG01-1000i (8BG55AV), according to: https://support.hp.com/us-en/product/hp-pavilion-gaming-desktop-pc-tg01-1000i/32480786/model/2100382..., is fitted with the HP Baker motherboard with SSID: 8767 (HP L75365-601 TG01 TP01 TE01 Baker Motherboard LGA1200).
Summarizing, your motherboard has two cooling fan power connections: one 4-pin labeled "CPUFAN" -which powers your CPU cooling fan, and one 3-pin labeled "CHFAN" -which powers your rear case "system" cooling fan:
Your rear-case system fan likely is a Foxconn model PVA092G12H, with these specs: 12V, 0.40A, 5-watt, dimensions: 92mm x 92mm x 25mm, or something like it:
Your question suggests to me that you would like to add an additional cooling fan. If this is the case, you may want to consider a more powerful cooling fan, rather than a timid 1-watt fan.
I don't have a diagram to show you, but I can share with you my experience what will work, as I have upgraded a number of legacy HP desktops, which needed additional cooling fans to bring processor/GPU temps down.
Without further ado, you can do this in one of three ways. Either you purchase a 4-pin cooling fan power Y splitter cable like this one*: 1 to 2 Way Braided Cable Y Splitter 3/4 Pin PWM Male Connector Fan Computer PC F | eBay, which you plug in the CPUFAN connector, or you can buy a 3-pin cooling fan Y splitter cable to plug in your CHFAN connector, like this one*: https://www.ebay.com/itm/124194064543?_trkparms=amclksrc%3DITM%26aid%3D1110006%26algo%3DHOMESPLICE.S....
Please note: "This is a 3pin fan splitter cable with black sleeving. 6" Length with Black Connectors. This cable is made correctly with the tachometer pin/wire running to only one of the connectors (fan speed signals cannot be combined)." -This means, that on the "Y" side, only one connector has three pins, whereas the other connector has two pins.
Same story, incidentally, with 4-pin Y splitter cables: on the Y end, only one has 4-pins (for the CPU cooling fan), and the other connector has three pins.
The third way would be to purchase a "PWM Fan Hub, PC CPU Cooling 4 PIN/3PIN Fan Power Cable Hub Splitter", like this one*: PWM Fan Hub, PC CPU Cooling 4 PIN/3PIN Fan Power Cable Hub Splitter Adapter Slee | eBay, which you plug into your CPUFAN power connector. The advantage of this method is that you would have 4 cooling fan power connectors, the disadvantage is that you'll have to get a 4-pin to 4-pin cooling fan extension cable, like this one*: Cooling Fan PWM Extension Cable 13.5 inches 22 AWG Black Sleeved 4 pin to 4 pin | eBay, in order to reach/power your additional cooling fan.
* = For illustration/show-and-tell purposes only. If you were to go with any of these examples, you may have to find alternative purchase options in Romania, including AliExpress.
All three ways are fine with regard to supply sufficient power to your additional cooling fan(s). Personally, I prefer method two if you are only going to add one extra fan, and no more.
Hope this was helpful.

The 1w fan is the Noctua NF-A9 FLX, consumption 0.84W, characteristics similar to the original one. I mounted this one in the case, and I want to mount the Foxconn one externally in the body where the PC sits (for better ventilation). I want to know if the power supply on the motherboard can power these two fans. Thank you again.
