Poor setup or new fans?

[Eastman51]

So I've noticed that my new GPU is running warmer than I expected (approx 10-15C warmer than last GPU). I have a feeling that its my case fans (not the stock ones), because the fans don't seem to have much airflow through the dust filters on my case.

I have a Fractal Design Define R6, with the 3 stock 140mm left in factory placement (2 intake front, 1 exhaust rear). I added my old Corsair fans (2 SP120, 1x 120mm with an LED), which the LED fan is having difficulty blowing air through the dust filter as an exhaust on the top. 1 of the SP120's is placed as an intake on the bottom, pointed at the GPU, which is blowing basically 0 air. The other SP120 is doing ok as a top exhaust. The stock fans are doing fine.

What I'm thinking is that I need to replace my Corsair fans with something much better. I've been thinking about getting some Noctua 120mm (or maybe 140mm) fans, but I also am considering some Arctic fans (the F series or the BioniX). Someone recommended me some extremely cheap looking Rosewill fans, which also had some reviews that hinted at poor quality (one reviewer said that the fan blades were hitting the fins on his radiator somehow). I've used some Thermaltake Riing LED fans on builds for my friends in the past, which seem to be quite good. But I'm not sure what I need for my setup.

 

I could also just have things setup wrong. Every fan (except CPU fans and the bottom fan) are plugged into the R6's included fan controller (all fans are DC, except CPU). The fan controller has 6 DC ports and either 2 or 4 PWM ports (not 100% sure). The bottom fan is plugged into one of the GPU's fan headers to allow the GPU to control it's own airflow. In the BIOS, I set a custom fan curve for both the CPU fans and the fan controller. The CPU has excellent temps, so thats good; but maybe I just need to adjust the case fan curve and move the bottom fan to the fan controller?

 

I'm looking for fans that can provide good airflow through the R6's dust filters, both intake and exhaust. I can fit 1 more fan, so I suppose I'm looking for 4 fans. Do I need high static pressure, or high CFM? Or do I need both? 

 

My CPU cooler is the Noctua NH-D15. My old GPU was the 1070 Strix, and my new GPU is the 2080 Strix.

thanks in advance

Dust filter on an exhaust fan???

The best fans in my opinion at the moment are the Corsair ML Pro

The dust filter is mounted on the top, and the filter has built in 'fins" (i guess) that angle towards the rear.  Technically I could use them as intake, but I thought that would be stupid.

Hmmmm. Not many of the Corsair products I've purchased in the past have been good (for me anyways), so I'm hesitant to buy anymore of their products.

You just need good air pressure fans.  What motherboard are you running?  Have you set up your fan curve?  I have the same case and use air optimized fans for the top and bottom of the case.  I can feel them moving air out of the case.  I'm assuming, hoping, you've removed the solid metal piece that covers the top vents.

I have a Strix B350-F, I've got a Ryzen 5 2600x. 
My fan curves are setup, I'd have to boot into the BIOS to get you specific numbers/%

I did remove the metal piece on the top (was a b to get off, lol).

You're running an ASUS Board.  Download their AI_SuiteIII software and let it set your fan curves. https://www.asus.com/us/Motherboards/ROG-STRIX-B350-F-GAMING/HelpDesk_Download/

 

If that doesn't help your situation you might want to look into more powerful fans. (Higher Max Air Flow).

So I'm not sure if they've updated/fixed AI Suite, but when I had that installed in the past it was causing my PC to randomly soft-crash. My screen would go blank, fans would max, and even reset switch wouldn't do anything; I would have to switch off the PSU and wait for all the lights to go off before I could boot again.

 

Also, from using AI Suite III on previous boards, all it really does is let you edit some* BIOS settings on-the-fly/while booted into Windows. So the fan curves I have set in BIOS would just be detected by AI Suite anyways.

*some settings require a restart, and its mainly just fan curves and CPU power settings that are available

What are the actual temps? What GPU was before and what now? Are these temps under load or...? It's normal that newer GPUs are hotter.

[GabeThePCHelper]

Can you give accurate temps instead of 10-15 c higher?

 

A higher powered GPU will produce more heat.

If you add 3 top exhaust fans to air cooled system, you might be making cooling worse. You are exhausting air that never reached any components. And r6 is not the god of cooling everyone thinks it is. I would try forcing more cool air to gpu. Something like what puget did with r5 to optimize airflow.

Just because they're $20 more expensive than other fans doesn't makes them the best fans out there

Bullshit, dude is probably bashing the brand with nonsense for being cheapo, all ""big"" reviewers do this on purpose to make users spend more cash on brands they promote, I wouldn't recommend too cheap fans for a build like that though.

Anyway, without removing those filters all fans will perform about the same being the only difference between them the noise level, static pressure fans are good for pushing air through filters or radiators but I don't think you could move the case filters at all so that'd be a no-go for you, high CFM would work better, Noctua, as Corsair is a bit overpriced for what you get (and how it looks, also you could get server fans or even Deltas for half of the price sometimes) BeQuiet fans look good and the prices are reasonable, Arctic is also a good choice.

 

Try to avoid Cooler Master and Thermaltake

I didn't write any global statement... It is just my opinion

https://cougargaming.com/products/cooling/vortex_pwm_fan/ I've been using these as case fans (3 wire) and CPU cooler fans (4 wire) for a long time now, I've had 3 or 4 that were in 24/7 operation for 3-4 years and have been swapped to another system which is running 24/7 now again. They move good air, they're very quiet, and they're usually around $15 on Amazon which is very reasonable given their durability and other wise good specs. I've had zero problems with any of the fans, no noises,  no clicking, no failures, no faults at all. I've never had fans that ran like these do for the lengths of time these ran. Even at full 12V their noise is unobtrusive with no shrill or harsh tones at all, just a bit of white air rushing noise. Their airflow is more focused feeling than other fans, whether or not they'll play nicely with dust filters I don't know 100% but they've got no problem pushing air through a heat Hyper 212, through cases, and through mesh case panels.

Sorry for the late reply.

My 1070 Strix idled at 38-43C, while under 100% load it would max at 65C. This was 5C lower than in my old Corsiar 100R case.

My new 2080 Strix idles at 38-43C, and while under 100% load it seems to max somewhere between 75 and 82C.

I would think that these cards should have similar load temps, they are both Strix cards so their cooler designs are pretty similar despite generational differences. The 2080 is a 2.7 slot card (meaning it has a thicker/taller heatsink) so the added cooling should be able to bring down thermals closer to the 10 series card. This is just what I think it should be able to do, idk if that's completely true.

 

If worse comes to worst, I could replace stock thermal paste with some leftover Noctua or Cryorig paste from my CPU coolers.

I don't have 3 top exhaust, I have a DVD drive installed so I physically cannot mount another fan at the top. If I purchased 4 instead of 3 fans, the 4th would be going in the second bottom slot as another intake. With that I would have 4 intake (2 front, 2 bottom) and 3 exhaust (2 top, 1 back), giving me positive air pressure. The second bottom intake, in theory, should help with supplying more air to the GPU; considering that the bottom front fan is level with the GPU and the top front fan is above the GPU and mostly blocked by installed 3.5" drives. I could also flip one of the top fans to be intake and slide it closer to the front of the case, theoretically improving airflow to the CPU cooler; but my CPU temps are excellent already, so I wouldn't think this would be necessary.
