NAS204 HD and CPU Temp
I purchased a NAS204 and I am using 2 WD Hard drives in it.... WD2001FFSX, 7200 rpm, 64mb cache, Red Drives @ 2TB each.
I am new to this NAS and slowly getting the hang of it. Seem to work well...

I just read the specs on my NAS 204 and it claims it is using a 92 mm fan, and that the operating temp is suppose to be 32 deg to 104 F, or 0 to 40C....
Mine unit is NOT running at the temps indicated in the manual of my RN-204
Now I am worried even more.... Unit is working correctly, but do not like the high temps.... definitely want to change out fans for Noctua - will doing that void my warranty?

The datasheet is giving you the ambient temperature range the unit can run at - not the CPU temp.

Yes it will void it.
You could try 6.5.0 beta, as it has a "run cool" fan control setting.
Your temps do sound too high to me. My RN202 has 6 TB Red drives which use ~5.4 Watts when in operation. Your 2 TB Red Pros use about 6.5 - more than the Reds I have installed, but not that different.. My system temp is 37C, the two drives are 28C and 30C - much cooler than yours. I'm running 6.5 RC2 with the fan control set to "run quiet". Maybe someone from Netgear will comment.

I decided to try and place a computer fan at the front of my RN204, in front of the drive bays. The fan is sitting on a small stand and is a normal chassis computer fan being run from an external power supply.
I wanted to try this to see if I could drop the temp by adding extra cooling, as I believe Netgear's stock fans are not sufficient.
By placing my 4" square fan at the front of the RN204 with the front drive bay door open, I have dropped my cpu temp from 58C to 44C, or from 136F down to 111F currently. I believe if I had a higher rpm fan I could drop it further.
I believe although the unit is working.... the cooling is not good. As I indicated before, this is a new unit I bought.... I did see you said it will void the warranty, but the excessive heat is unwarranted and could further fatigue my hard drives too.Netgear, do you have any explanation why it is running hot? I have only had this running for almost a week..... new out of box.

Those temps are fine. If there was a problem there would have been alerts about it.

I agree they are safe, but I'm not convinced there is no issue.
The temps are certainly higher than I'd expect. And there is some evidence that running the disks at lower temps will prolong their life. For instance figure 5 here: https://www.cs.virginia.edu/~gurumurthi/papers/acmtos13.pdf.
Perhaps some other RN200 series user who is using WD Red Pro disks can share their temps.

What speed are they running at? Also, what is the ambient room temperature?
Is the volume still being synced/built? That will increase the power used by the disks (and the heat they generate).
I suggest trying the "run cool" fan control setting in 6.5.0-rc2 before you jump to a conclusion on the stock fans. You should be able to downgrade back to 6.4.2 production firmware if you like.
