Recommend Cooler for 5800X3D

I bought an AK620. Noctua a bit too much. Assassin would've been the next choice. It's incredibly annoying though as it hums when it revs up every 10 or so seconds. Tried flattening the fan curve in bios but still revs up every time I do the most basic of tasks.
I'd just shift the curve the other side of whatever your everyday temp is. Mine only really ramp up if gaming and the temp is getting towards 70°C+. Definitely just a matter of playing with the curve a bit. Mine sits around 41°C doing desktop work.

also make sure you're setting the detection frequency thing - i forget what it's called - to 3 seconds. This stops it revving up for momentary pops above you target temp.
 
Mine installed yesterday at stock settings - max is 83 degees using an 11 year old Noctua NH-D14 when running cinebench, idle temp 55 degrees. Voltage is maxing at 1.256v and all cores run at 4.55ghz on a 4 year old B450 MSI Pro Carbon AC mobo

Be good to share your experiences with the cooler on the 5800X3D.

I have a 5800X3D myself and its definitely a toasty CPU on stock voltages. I have a Brocken 2 with dual 140mm fans that tames it at around 83c when running Cinebench.

Run an extreme test like Prime small FFT torture test and it hits 90c within seconds and thermal throttles!:eek:
OK so just got the CPU installed with the Thermalright Peerless Assassin 120.

On Cinebench the temperature topped out at 73°c and frequency sitting right at 4200mhz with a score of 13624.
On Prime Small FFT test it went to 90°c within 30 seconds with the frequency fluctuating between 4060mhz and 4080mhz, I only ran this for about 15 minutes.
 
Dont be so complacent these run HOT.....Also make sure you look into PBO 2 as well.

I would really recommend you take varkanoid's advice and look at PBO2 Tuner, this can not only improve performance but also knock some degrees off your temperatures my settings are -30 on the curve for all cores, 120W PPT > 70A TDC > 110 EDC.

You could also look at a negative offset for your VCORE -0.05 gives me the same performance as auto but also knocks off a few degrees from core temps. An offset of -0.1 is still stable and makes a massive difference in temps but performance is not quite as good.

Mine idles at 28c, ambient room temp currently 25c ;)

Its a no brainer with a 5800x3d. We are not just saying it for giggles loads of people do it and benefit.

Yes, undervolting is the right way to go with 5800X3D if you want good all-core performance. Either in PBO2_Tuner, or PBO in the Bios, if it's supported (mine is). -30 all cores seems the common opinion. I had to undervolt further (-0.05) when pushing the memory and IF to 3800. Could go higher, but WHEAs resulted (use HWInfo to find), and had to move other voltages up a bit to get stability at those memory settings (ie no wheas or memory errors).

Personally, I used the Scythe Fuma2 (the first version), but upgraded it to 'B' version with faster fans. CB R23 runs at about 78C, and I'm happy with that. Good twin tower cooler, height around 155mm which fitted my mid-tower (glass panel) easily. Looks big and dominates the case!
 
currently maxing 79c-80c with cb23 multi run scores 14800-15000+ this is with using z73 360aio the 3 rad fans at 800rpm , -30 all cores . setting -30 really made difference to the temps lowering power and increasing points in CB
still nagging me seems high when using 360 aio I blame the motherboard bios just not playing optimal with cpu and offset is broken MSI x570 unify, also its better with older bios its 75c cb23 but doesnt have the PBO in bios which the latest one does and if I can help it dont want to be adding extra stuff into windows setting pbo tuner so gone back to the latest bios as during gaming its averaging 50-65c stays at 4450mhz so seems fine

hope msi release newer bios and improves it pairing with the 5800x3d

I seem to be stable at -35 anyone else have something below -30?

currently maxing 79c-80c with cb23 multi run scores 14800-15000+

Getting similar results but most importantly managed to knock ~10c off the temps was hitting the thermal limiter before. Seems crazy that this isn't available in Ryzen Master/BIOS especially as Task Scheduler refuses to save so I have to set it manually each login, gah

So i have the system in my sig, i have enabled the PBO in the BIOS and lowered PPT to 110, TOC to 75 and EDC to 100 and set a curve of -30. Is there anything else i should tweak at all to get lower temps?
 
You could try a negative offset to vcore, I run -0.0500v any less and the cores don't sustain max boost. I also found lowering PPT TOC & EDC dropped boost clocks so have left these stock but YMMV.
 
So OCCT would appear to stress the CPU more than Cinebench, whilst stressing with OCCT and Ryzen Master open I can see the values of the PPT, TDC and EDC and only the EDC is being maxed at 100% so would that suggest for the PPT and TDC that I can lower these values even more in the Bios but maybe I need to up the value of EDC as that's being maxed out??.......the system is stable though and hadn't crashed whilst stress however

I've been looking at this cooler for this CPU tbh.(well, the PS120 at least)
looks like a good option unless you're willing to spend mega bucks.

I initially used the Brocken v3 I already was using on the 3700 I updgraded from but as a large retailer reduced peerless assassin to £32 in their recent sale I decided to go for that given all the positive review. On Cinebench by the end of 10 mins with the Brocken CPU temps had reached 85C with CCD hitting 90.5 at max. Initial results from Peeless Assasin were disappointing - went to 90C very quickly ... but I'd had issues getting it installed as it didn't seem to fit well. I then realized that the Broken was using an Alpenfohn AM3->AM4 conversion kit I'd got with the Broken (which was originally designed for AM3) and I'd had need to use a mix and match between what the Brocken had used and thew new mounting kit to install the PA. When I realized this I managed to dig out the AM4 backplate from the motherboard that I hadn't been using. Removed the PA - could see from the thermal paste that it had not been in contact with one side of the package - reinstalled the mount with the correct backplate and the PA. Just run cinebench and its topping out at 75 now after 10 mins. So (if fitted correctly!) its doing 10-12C better than the Brocken (and 8C better in the L3). So looks like a good choice in the end!
