CPU Cooler / Need some help!

Greetings all,

It’s been a little while since you all helped me pull together my current build—I owe a huge thanks to Corsair specifically

Now, I’ve reached the point where I need to swap out the stock cooler that came with my CPU. It’s started making itself known lately—getting loud enough to be a real nuisance—so I’m looking for some guidance...

I'm leaning toward those low-profile coolers; they just look cleaner in the case. I’ve got my eye on either the Intel unit (around $107 Best Buy) or the Noctua NH-L9i (roughly $100 Micro Center)

I’d love to hear what you guys think. My main priority is just finding something quieter—my budget is pretty tight, though... $107 Thanks.

Since you're running a non-K processor and won't be doing any overclocking, you could easily go with something like an RTX 4090 which is a fantastic cooler for the money and much quieter than something like a Raijintek Nvidia, which sits in the same price bracket. You could always go with Noctua, of course, or something even pricier, but honestly, since you have a non-K chip, I don't think you really need to.

You can actually overclock a non-K processor; you just need to know what you're doing. I recently saw two buddies of mine overclocking their non-K chips right in the BIOS.

Yeah, if you're willing to risk frying your CPU just to squeeze out an extra 0.1 GHz, how much of a gain are you actually going to see? 🙄

I don't know the first thing about CPU Overclocking—so I'm definitely not touching that—but I am curious: how much louder is this recommended RTX 4090 cooler compared to a Noctua setup?
Honestly, if it’s significantly noisier, I’d rather just cough up another $50 extra bucks to get some peace and quiet, even if I'm probably overthinking it...

I keep seeing people rave about Noctua coolers and fans being practically silent, which is why I'm looking into it in the first place. 🙏

Honestly, Noctua is easily one of the best air coolers you can grab right now—if money isn't really an issue for you, I’d personally just go with the Noctua NH-L9i.

Yeah, like Larry Ortiz5 mentioned, you really can't go wrong with Noctua. It’ll definitely be quieter than the RTX 4090, but honestly, the liquid cooler should be plenty quiet enough—unless you're some kind of total noise freak 😁—and it'll keep things just as frosty. Even the stock setup does the job. So, look, if money isn't an issue or if you don't mind dropping an extra $57, then yeah, go with Noctua. Their coolers are top-tier. But if you'd rather spend that extra $57 on a night out grabbing burgers and beers, just stick with the liquid cooler or something similar 😬

Are you absolutely certain the CPU cooler is the one making that noise? Looking at your setup, I wouldn't bet my life savings on it being the cooler; it’s much more likely to be

- the power supply fan
- your GPU (especially when both are under load)
- those stock fans in your Zalman case

Two months isn't nearly enough time for fans to start making noise, and it's definitely not enough time to build up a layer of dust...

I guess you can never say never—you might have just gotten stuck with a dud component—but if you went with a Fortress unit, I doubt it's whistling, and honestly, even with a Zalman case, they pack decent 120mm fans inside...

Do yourself a favor and actually think about what's bothering you and where that sound is coming from...

I’m not saying it’s loud, per se. It’s just that a higher-end Fortress Raider unit supposedly gets a bit noisier under heavy loads—especially when you're running an R9 290. Plus, I remember someone on this forum complaining once that the stock Zalman fans in those cases were incredibly loud, though most people don't find them to be an issue. Look, high-quality fans cost about $6 or $7 apiece, but in the Z3, you get three of them included (four if you grab the Z3+). If they were top-tier premium fans, the case wouldn't be such a bargain, but even so, it’s easily the best value case at that price point. Of course, noise sensitivity is totally subjective. He's also rocking an R9 290; it isn't using the reference cooler, but even then, under full load, it can definitely be "audible," so to speak. In my book, the stock cooler on an i5 is the last thing I'd worry about.

Anything is possible, I guess. But honestly, every Z1, Z3, and Z9 I’ve ever worked on or owned came with Zalman fans that actually performed well. Since they design their own stuff, they probably factor those fans into the cost anyway instead of charging extra for them. 😬

Have you messed around with the CPU fan curves yet?

On my i3 Haswell build, the fan settings were aggressive enough to kick the speed up to 100% the second the frequency spiked—even without a full load.
Now, even under load...

The stock Intel coolers aren't exactly top-tier, but an i5 isn't exactly a power hog either.
I’d suggest someone chime in with what they consider acceptable idle and load temps. Set the fan to target those numbers, and I bet you won't even hear it running.
Especially if you grab a liquid cooler; I reckon you could keep an i5 around 60°C under load without breaking a sweat.

An extra 120mm fan will be way quieter than the stock cooler anyway, and it'll rarely need to hit 100% if you dial in the settings right.
