2nd opinion on cooling solution for Ryzen 1700

Been discussing this in the primary Ryzen 7 CPU thread, but figured a 2nd opinion here couldn't hurt.

Basically I've got a Ryzen 1700 setup, that I want to do some moderate overclocking to while still keeping things very cool and quiet. I don't want to push the OC to it's limits, and will happily sacrifice power in order to keep the system running as cool as I can.

Unfortunately the Cryorig H7 I got for the build isn't cutting it. Even at 3.6GHz, the cpu is hotter than I'd like (70+) under stress tests.

So I'm looking to upgrade, and have been looking at going right to Noctua D15. It's probably overkill for what I need, but I don't mind overkill if it means I'm going to be running cool. It fits my case/RAM, and the price isn't a huge concern for me.

My only question is, are there any downsides in going overkill with something like the D15 over the smaller like the Noctua U14-S? Like, would the D15 be louder since it's got the 2 fans? Or is all that added weight something that would impact the motherboard overtime?

I'm sure I'd be good with the U14s based on reviews, but if the D15 is going to perform even better, is there any reason not to get it?

I would second the opinion to fix your fan curve. If you didn't touch the fan curve there's a chance your motherboard is using fan curve for Ryzen 7 1700X CPU instead, which means there is a possible wrong fan curve from the motherboard (Ryzen 7 1700X has a +20°C T_ctl offset to have a more aggressive fan policy). The H7 should do fine for 3.7-3.8GHz with 1200 -1300 RPM fan speed , provided you keep voltages low (~1.2 - 1.3V , stock is ~ 1.225V for Ryzen "X" CPUs).

Don't get the Noctua coolers if you're on a budget and are on the AM4 platform.

Thermalright's offerings are the best bet for AM4. Every cooler built in 2017 has AM4 support.

The Cryorig H7 is a 140W TDP cooler while the H7 Quad Lumi is ~ 160W TDP cooler (the rating is based off the full 1600RPM fan speed) due to an added heatpipe.

A Ryzen 7 CPU at ~ 3.9 - 4GHz consumes about 150-200W depending on how leaky your CPU is.

I would personally recommend something like a 200W rated True Spirit 140 Direct or 240W rated Macho Rev B. if you want to see real improvements and can fit 165mm tall coolers like the NH-U14s and NH-D15.

I have fiddled with the fan curve some, but at full speed the Cryorig H7 is louder than I would like. I'd be aiming to keep the fans from ever reaching top speed.

I think my issue is that my 1700 chip is particularly power hungry. Even to get something as minimal as 3.6GHz I need to feed it at least 1.25v. 3.7GHz is 1.3v and that's not even 100% stable yet.

I'm not creating a budget build at all, virtually everything else in the machine is on the higher end. I would have had no issue's spending more on a better cooler, but was told the H7 would be enough to do minor overclocking with.

And they are probably right, but not at the noise/temps that I want. At least not with my chip.

Your case fans need ot be spinning fast enough to supply CPU and GPU coolers with cool air. The temperature when you first start computer should be the same as what you have 10-20 minutes later if only surfing the web or other light loads. The fact your temp is higher after awhile is a good indicator your case isn't moving enough cool air.

What is stock voltage?

AFAIK the Ryzen 7 1700 stock voltage is around 1V.

Anyway 3.6GHz from 3 Ghz is +20% over stock base clock

I don't think my temps are creeping up over time. My idle temps stay in the mid 30's, if I'm just doing light work. I did test out my case fans, as I initially thought they might be a problem. I opened up the front case door and removed the dust filter so the fans had zero obstruction for airflow. Overall it didn't have a big impact, 1 or 2 degree's tops while the system was under full load.

That was an option I've been considering as well, but I haven't been able to find much good data on what kind of impact fan quality makes.

I believe stock is around 1.187v. And 3.6GHz I'd be totally happy with, and I was initially when I thought I had a stable OC with temps that only got into the mid 60's. But I started seeing WHEA errors when running real bench, so I still needed to add more voltage. And as I added voltage, temps started going up. At 1.25v, temps are now in the mid 70's and I still see a WHEA error (though very infrequent) which tells me I still need a little more juice. But I'm already above my thermal threshold of where I want to be

That's too hot for AMD. You need a decent aftermarket cooler. Something with some copper a 120 mm fan that pushes air.

I was running AMD with a Silenx Effezio 120 and a Panaflo strapped to it. Temps never went over 58c @ 4.1Ghz full load with 1.385v.

IMO, there's just not enough mass to dissipate the heat in the cooler you're using. The chip will overpower it.
