A computer technician that does not know the difference between TDP and PPT. Very impressive.
Also reluctant to renew his 30 year old knowledge about CPU temps, boost behaviours and thermal limits.
This will help you:
And surely the CPU will just vaporate at 80C.
You might not know that but a tdp rating and and the actual power draw are 2 completely different things.
You might not know that but activating ECO mode sets the PPT actually to 87W - not 65W - so it just changes absolutely nothing in my examples above.
I have no problem - i already solved...
I link my experiences here, may be helpfull: https://smallformfactor.net/forum/threads/7800x3d-experience-and-discussion-this-thing-is-great-but-can-run-hot.18470/
Hey - a summary of my experiences in a SFF build.
I switched from the 7600X to a 7800X3D in my Dan A4 with a Noctua L9a with Duct.
Running with PBO -35 stable, CPB enabled.
Everything went great - the CPU is super efficient in gaming, hitting not more than 50W and 75C in most of my titles...
Differences between all below 47mm coolers are minimal with the 7800X3D. The CPU draws nrarely more than 55W while gaming and just every cooler can cope with this jsut fine.
With an L9a i get 94% all core performance at 82W sustained and just full gaming performance at 75-80C for most games.
30 bucks for the ASUS are definitely worth it for better sound with AMP, USB-C display out, PCIe 5.0, ... The MSI should cost less than 200 bucks in comparison.
VRM designs are very much overrated outside of Extreme OC - which is not really a thing in SFF builds anyway. Any board can drive any CPU without problems and headroom left.
PCIe 5 for SSDs is also very much overrated - you need either active cooling or an absurdly big cooler on the SSDs -...
The Gigabyte diagramm does not show them on the same lanes - the line shows that they are on the same bus (PCIe 4.0). Still the PCIe has 16 Lanes of its own and the NVME has 4x lanes.
The Gigabyte has a little bit strange layout and a small daughterboard. So you have to look into the cooling...
@rfarmer "Required" was meant in relation to the statement of OP that BIOS flashback is required by AMD for all B650 mobos - which it isn't. It is indeed very usefull and i personally would not buy a board without it.
Seems to me you are just guessing alot.
What are the ASUS BIOS problems about? I cannot recall BIOS problems with my X670E-I.
Source for the Asrock OC claims on AM5? In the end you will most likely use PBO anyway and not use factory settings.
BIOS flashback is not required - it is part of the...
@k0n Limiting an AM5 cpu to 65W would still mean 87W power draw - this should not be forgotten. Still a L9a with duct can cope with it.
I like the idea and it mgiht be worth it if a 4070Ti with 16Gb sees the light of the day. The PNy single slot cooler is good enough for 200W - the 4070Ti would...
You just do not tighten the screws all the way down.
Have the same "problem" woth my X670E-I but i recognized it while assembling and just reacted accordingly.
With these temps he very likely did something wrong with the assembly of the SSD stack. No SSD reaches these temps normally.
That is what i told him on reddit too.
