Be Quiet! Dark Rock 3 Idle temps? With FX-8350

[Cookie-Cudi]

Just bought the Dark rock 3 and its in the postage and I am just curious on what the idle temps are like?
and the load temps at 4.0Ghz

I have the Bitfenix Ghost Case with 3 in-take vans and 3 exhaust fans.

I originality had the H80i but oh my god it was soo loud. i am talking about 75db and a bloody whine from the fans. haven't changed fans for it but i just hate it already. Sold it to someone else already.

Love a reply thanks!

All the testing sites used Intel processors for benchmarking, but you should likely see between 20°-30°C with an FX chip depending on the number, type and speed of the fan profiles used in the case fan locations. Maybe a little less if airflow through the case it really, REALLY, good, but I'd count on 20-25°C.

There are too many variables to estimate what your load temps may be. Overclock settings, voltage, case airflow and configuration, mounting pressure, thermal paste application and the chip itself (Some are just better than others, that's while it's called the silicon lottery). The type of load also matters. A full game load, rendering loads and Prime95 small FFT stable state loads will all be different. As long as it stays below 65°C, preferably no more than 60°C, it should be good.

I can't say as to the idle temps since I don't have an fx 8350. You might be able to find some comparisons online, but much of it may have to do with your case, it's location, the actual performance of the fans used in the case and of course the ambient temps in the room where your pc is kept. Ambient temps and case airflow are all part of the cpu cooler equation.

I have the dark rock pro 3 which is very similar to the dark rock 3 and I can say it's pleasantly quiet. Even on an overclocked 4690k. I wish the be quiet fans had more availability in the u.s., they're pretty limited and when they can be found are really expensive. According to frostytech, the h80i at full speed is 64db. No listing for low speed. The dark rock 3 at low speed is 29.5db and at full speed is 41.8db - a fair bit quieter than the h80i.

Dvtests tested the fx 8350 with the dark rock pro 3 which should be similar to the dr3 you ordered. With room temp of 18c (64f) at 4ghz 100% load across all 8 cores under prime95, core temps were 46c and that was with 1 fan. A more even comparison since the dr3 is a single fan cooler.
The temps went to 57c under load at 4.4ghz oc.

I'm EXTREMELY skeptical about them running those tests in a CLOSED system, WITH AVX at 1.4v@4.4Ghz and still getting that low of a temp. Usually running AVX on an FX chip causes temps to become unrealistic, but I'll leave it at that since I can't say for certain that there's any funny business involved in that review. Suffice to say, it's a damn good cooler even if it is too big and too, black. Heh.

Lol, I like the looks of it. Personal tastes vary of course. I don't know about the specifics of running avx on the fx 8350, not as familiar with that combination in general. I did notice their ambient temps were a bit cool which may have helped. It doesn't help much since the 4690k isn't the same cpu, but running the drp3 with ambient temps around 21-22c right now, my idle temps are 25c. If ambient temps were similar with an fx 8350 idling with the single fan dr3, i'd guess around 26-28, maybe 30c if that. Just guesstimating here, so don't shoot me 😛

Actually, idle temps don't concern me since the AMD sensors are notoriously inaccurate below 30°C. To clarify that though, clearly lower is better than higher since there must be some relation between relevant temperature and lower numbers, regardless if the actual number is correct or not.

What does concern me, and should be more tightly focused on for most users regardless of chips used, is the upper temperatures. Now don't get me wrong, this is no bash on the DR3, at all, but rather just information. It doesn't matter if the cooler you use gives you temps that are somehow equal to ambient, or even lower, with say, a Peltier cold plate, if the high temps can't be managed below TjMax (The point at which you've exceeded the specified thermal limit and throttling begins.) using non-AVX steady state temperature load testing.

It just seemed odd to me that they were able to achieve those temps considering all the factors that were working against them but I suppose with a dual fan cooler and now that I notice the extremely low ambient temperature of 18°C I understand. All things considered, with an ambient temp of about 23°C, which is more realistic for most rooms, they would probably exceed the 60°C thermal recommendation for the 8350 or be right at it. Without running AVX, and with a slightly lower voltage, they would probably have been a bit lower though, which is ok.

Most these test sites, especially the less experienced testers, generally run higher voltages than is necessary simply so that they don't have to do a lot of fiddling around with determining stability on their test rigs. With a lower voltage on the overclock it probably would have had better results.

Yeah, guys for a water cooler with a massive amount of air flow and for some reason working its jardest I was idleing on 45 degrees in my bios and on speed fan. Speed fan is extremely accurate with cpu temps and is closest to the BIOS temp.

Not sure if you know about the AMD CPU dropping frequncey at 65 degrees to lower the temperature? I got massive lag spikes in games because of high temps.

Hoping I dont have to buy a intel i7 and 200 dollar motherboardjust to fix the damn problem. Some guy said it was something like passive cooling in my power settings but I was unsure were and I couldnt find it. Got any ideas?

IF your fans are managed through your motherboard headers, then using the performance setting in control panel, power options, is the best way to ensure you don't have the processor power management cooling policy set to passive. You can go into Control Panel, Power options, and select the Performance profile, or click "change settings" next to your current profile, then click "change advanced settings", scroll down to Processor power management and make sure min/max are set to 100% and under system cooling policy, set to active.
