Does an onboard GPU make the CPU hotter?

I have my homeserver over here, and the AMD processor on it gets pretty hot. It also has a Radeon R5 onboard GPU with it. So I was thinking, what if buy a cheap a$$ passive cooled GPU for this system, would that even help in keeping the processor cooler? Or does it not even matter? Note: this home server is attached to a monitor but that one is always off. I control it though Remote Desktop and through Shares I can get to my files.

The integrated Radeon R5 GPU doesn't use much power as it is, so it's probably not the cause of your CPU woes. It's not like you have a GPU that pulls 100w or even 200w of which spits out a lot of waste heat. Most likely your heating issue comes from a problems with the CPU cooler, a weak CPU cooler, or the chassis has poor airflow.

Now, If I put a larger GPU in a case that has poor airflow then Yes! the CPU will run hotter. 

These old AMD A-Series APU's with 4-cores and a higher clock speed will run on the war side.

Only by about half, keep your eye on it though.

a better cpu cooler is what you want ... and cheaper, too

When you say
- it gets pretty hot
do you mean
A - it gets dangerously hot, hotter than it is supposed to get, hot enough to set off the system overheating warning alarm
or do you mean
B - yeah, I felt it, or yeah, I checked the temp with software, and it's hotter than I expected...but not hotter than it is supposed to be according to the specs, and not hot enough to set off the warning alarm

if A
then get a new, better cooling fan/heatsink combo

if B
who cares?

You say "It also has a Radeon R5 onboard GPU with it."
I assume you mean: a GPU combined with the CPU in a single chip.
(AMD A8 CPU, for example).

Likely adding a video board
combined with ***disabling*** the motherboard on-chip GPU in BIOS settings or by some other means
will indeed significantly reduce the CPU operating temp.

I can't say if you would see more improvement with a better fan/heatsink
or
if you would see more improvement with a new add-in video board and disabling the on-chip GPU.

Technically it does but its MAYBE 1-2 C at max. 
a cheap passive gpu will heat your computer more (as they can produce much more heat)


just buy a better heatsink instead.
