Is my P400A fan placement bad?

Recommended Posts

Posted · Original PosterOP

I purchased the Phanteks P400A-D case based on GamersNexus reviews on thermals. As well as the 3 stock fans in the front, I've bought a Be Quiet Silent Wings 2 (120mm) for the rear exhaust and a Shadow Wings 2 for top rear exhaust - the top front slot is empty.

 

I'm getting quite poor temperatures all around - CPU temps are 45-55c on idle, 75-80c whilst gaming, GPU temps are 5c higher than benchmarks I've seen (70-72c whilst gaming). 

 

The fan curves are fairly aggressive for all fans - they ramp up to 100% at 70c gpu/CPU respectively

 

The important specs:

 

Ryzen 7 3700x

MSI RTX 2070 Super Gaming Trio X (not vertically mounted FWIW)

Asus ROG Strix X570-F

Wraith Prism RGB Cooler

Phanteks P400A-D Case

EVGA G3 power supply (eco mode OFF)

 

 

 

Is there anything I can do to improve my fan setup? Is my top rear fan necessary?

 

Any tips are appreciated.

Maybe room temperature is just a bit high?

Room temp is around 21c which is fine

Just take the side panel of the case out. If it still gets hot, your case fans arent the ones to.blame

GPU is normal, CPU is on the higher side. What CPU cooler do you have?

Both GPU and CPU get quite a bit cooler with the side panel off (4c and 8c respectively), which means the case fans are to blame in that case?

It's the stock wraith prism RGB cooler. I'm looking to upgrade it to a smaller mid-sized cooler but still surprisingly high.

Easy to try without the roof fans is it not?

Yeah I suppose it is. I was more asking of a general consensus of whether or not the top fan is advised or not

Yup. I assume all fans are at max speed, top and back are exhausts?

Yes, they all hit max at 65c. Top and back are exhausts. Front 3 are intake obviously. I've retested over a longer test and it's a 3c GPU difference and 2-3c CPU difference with the side panel off, which really isn't that massive. I assume a little bit of difference is to be expected with the side panel off?

 

I've taken the top fan off and ran a CPU stress test and CPU average increased by about 0.7c, so there is a little bit of benefit in that fan, but not much. This fan is above and slight to the left of the CPU cooler so there should be no negative impact with it (i.e. exhausting fresh cold air like the front top would have done)

Then maybe the thermal paste on the stock cooler is bad? Not like the cooler is that good from the beginning

I think I'll upgrade to a better cooler. Maybe a NH-U12S or Arctic Freezer 34 Duo (I hate the thermal paste application on this cooler though). FWIW I did remove the stock thermal paste and apply my own MX-5 (not that this is the best thermal paste around but surely better than stock). 

 

I assume the GPU temp differences from reviewers are because they test it on an open bench. 

 

I'm just wondering if I can justify the £15 for the 1c~ temp changes for the top fan. I guess as long as it doesn't have any negative impacts then it's not the worst, but I expected slightly better temps with the top exhaust.

Ok, I'm starting to notice trend with 3rd gen Ryzen. The temp is actually normal for the CPU. The cause is AMDs PBO (Performance Boost Optimization or something like that). It raises clocks and voltages to squeeze more performance out of the CPU if cooling can handle it. Looking at multiple threads about this, looks like target temp is 80C.

 

So to lower temps, disable PBO. The performance hit will be minimal.
