I’m curious to know if temps change when you pop out those disk covers so the top fan then has some air to work with.

also... intake? @Jax-Ur

[RevGAM]

@Jax-Ur
@NorKris and @Ralfi have good points. Remove the bay doors and flip the rad fans around so they're intaking instead of exhausting and see if that helps.

[Jax-Ur]

With the front door open and running Cinebench R23 for 60 minutes (for both tests) the results are even. With the two 5.25" panels on the temperature was a solid 77°C, with the two panels gone (better air flow) the temperature fluctuated between 76°C and 77°C, mostly around 76°C with some peaks for a short while at 77°C.

 

Room temperature was around 23.6°C

 

So the two 5.25" makes no noticeable difference in this particular case.

 

@RevGAM I flipped the AIO fans a few days ago and they are in intake mode.

 

Edit: added chart below

 

Here is a chart for the ~60min that it ran with the door open.

OPEN = 5,25" bay trays are removed, better air flow for third AIO fan

CLOSED = 5,25" bay trays are in place, poor air flow for third AIO fan

 

If you go with the Tctl/Tdie values then there would indeed be that one 1 degree difference. If you go with CPU die then there is next to no difference.

 

These are all averaged out from a data set of around 1835 data points (30 data point per minute) collected by HWiNFO64 7.66-5271 during 60 + 60 minute run.

what side was the fans on when  u did open the front?

Oh, sorry, I thought you were trying to confirm intake or exhaust.

Yeah that’s another comparison I’d like to see - whether a push or pull setup makes a big difference.

 

Having never used nor delved deeply into AIO use, I’ve always wondered which is the best way to go:

• Having intake AIO fans push fresh, cool external air over the radiator, so you’re cooling the liquid more so, but also potentially heating the inside of your case via blowing the heat that’s travelled from the CPU into the radiator.
• Or having exhaust AIO fans push the warmer, in-case air over the radiator, so the liquid won’t be as cool. In this scenario, would you need a higher RPM to improve cooling efficiency, compared to an intake setup?

thats an known factor.  push is better than pull

You're killing me, @Ralfi! I'm halfway done with seeing if the MSI results can be replicated (halfway because I have a large enough case that I have to use a vertical mount for the front and side, so I have to also do it with the GC in the mobo slot).

Just remind me that you want to know about that, too, ok? I'll get to it.

They are currently pulling intake through the AIO radiator. I want to test mounting two 140mm like I had with my Noctua NH-U12A that would push air through the radiator but I need to find longer screws to mount them properly as the 25mm that I used before are not long enough now that the radiator is mounted.

 

Once I get this setup I'll run Cinebench again and see if the temperature drops further, it should in theory at least as it pushes cold air through the radiator.

yes, pushing in is better than pulling out... dont think dirty now

I like it both ways. Oh wait, you were talking about cooling a rad. My bad.  

[Jax-Ur]

I was unable to find correct screws in any of the hardware stores I visited today so I had to McGyver the 140mm fans in front with zip ties. I ran the test without the front dust cover as it would not fit due to the zip ties.

 

After running Cinebench twice 60 mins with 5.25 bays closed and open here are the results and with two 140mm front pushing air through the radiator (and the three 120mm pulling air through the radiators here are the result. I have split the graphs into two for easier reading.

 

Room temperature ~23.4°C

3x120mm 5.25 COVERED = 5.25" bays covered, three default AIO fans pulling cold air through the radiation

3x120mm 5.25 OPEN = 5.25" bays open, three default AIO fans pulling cold air through the radiation

 

3x120mm + 2x140mm 5.25 COVERED = two 140mm fans in front pushing air through the radiators, 5.25" bays covered, three default AIO fans pulling cold air through the radiation

3x120mm + 2x140mm 5.25 OPEN= two 140mm fans in front pushing air through the radiators, 5.25" bays open, three default AIO fans pulling cold air through the radiation

 

 

 

 

 

Edit: for whatever reason running with the 140mm fans pushing air and the two 5.25" bays closed looks to yield a slightly better result.

Edit2: new charts with hopefully better colors

but im confused.  Average of CPU die C   No fans? closed   vs  Average of CPU die C 140 closed

closed = means the 5.25" bay door closed, those two seen at top of the picture below. The case front door is open in all scenarios.

 

Also in all four scenarios the three AIO fans pull air through the radiator.
