Fan for NH-D15

[jm_bmw]

Hi everyone,

 

The original 140mm fans doesn't fit the case, so I replaced with a 3pin 120mm one, just one in the middle. Temps are ok in games (60-70C) but if I stress the CPU it will easily reach 88-93C. Fan curve is already tuned + undervolt.

 

I am looking to replace with a better 120mm PWM fan, and here comes the first question, will it matter/worth at all?

 

If yes, filtered down to these 3 models that are available here:

-Akasa Viper

-BQ Silent Wings 3 High-Speed

-Scythe Kaze Flex RGB 1800rpm

 

Also not sure about flow vs pressure design for this heatsink...

You do realize what the words "stress test" mean right?  If a stress test doesn't push your chip to throttle, your cooling is more than adequate.

 

Your temps in gaming are good as well.

 

You're overthinking this.  Your cooling is fine.

What I would recommend is the included Noctua fan. Can you clarify exactly why that wouldn't work?

Cannot fit due to tall RAM heat spreaders (RGB probably)  and case won't allow for clearance. 

 

You should be able to fit the 140mm in the middle of the two towers though. I'd just pick up a NF-A12x25 for the second fan if you're that worried about temperatures.

My bad I didn't explain it well. Right now it stays like this due 24C ambient, but in hot days like 30-34C here it will thermal throttle in stress tests and games that use more cpu (like ACO) will reach 85C in some cores. I thinking that a higher RPM fan will help.

Yes, the case side panel doesn't close, the fan stays mm's higher than the heatpipes and due being a glass I can't flex it.

Are you sure the cooler is mounted with the correct pressure? Nocuta's mounting system is arguably the best for air coolers, but I'd expect the D15 to do better than that. Unless the 9900 is an extraordinarily hot chip. IDK...

 

I'd put in another vote for the NF-A12x25 fans as @SpiderMan suggested. They are awesome. A bit pricey, but awesome.

If you really want to replace it just get an arctic p12 fan. Noctua performance super low price.

The problem with NF-A12x25 is that it is available in just one store down here and costs 3-3.5x more than the ones I mentioned. I mean... I would rather add more ram for this amount of money.

 

@RAS, yes it is mounted fine, hot days really change things up...

 

@Jaslion, it seems like arctic's CFM is lower than the deepcool I am using... how acurate those companies numbers vs marketing are IDK...

You could always try one of noctuas p12 or f12. And if you really can't do those there's always corsairs ml120 though it's ungodly loud.
