If air get the new zalman cps20

It is not by 8c it is 3-4c in the Kitguru review.

It looks promising and definitely looks better than the stock older beige fan D15. I'd personally wait for a few more reviews/comparisons between the Chromax D15 before drawing any concrete conclusions.

(I've seen a German review that shows the D15 as very slightly better than the Zalman, within margin of error)

ZIP of mixed testing Micron E die 3800MHz of ~31hrs continuous uptime, organise files by time.

Filenames at beginning have:-
  • Setup means test on POST when profile setup in UEFI.
  • FCP means a full fold POST, ie power supply switched off from wall prior to POST.
  • FP means a full POST from shutdown.
  • WP means a warm POST test run.
  • SPx means count of testing on same Post.
  • When a filename is repeated exactly, just capturing data of the same test run but later.
This screenie, left to right:-
  • 3x AIDA64 for usual timings I use on Samsung B die
  • 3x AIDA64 for current timings I'm using on Micron E die.
  • Initial testing for the Micron E die profile as used for 3x AIDA64.
  • 3737% RAM Test for 3x AIDA64 3800C16, but VDIMM 1.365V.
*** edit ***

An updated ZIP, organise files by time. On Micron E die 3800MHz Phase 1 mixed testing of ~48hrs continuous uptime. Phase 2 I have lowered VDIMM to set value of 1.36V, from past experience with board a read with DMM on Probeit point for this would be ~1.364V.

Looking for some help all please?

I've just taken delivery of my new OC Build which has a 3900X on a Gigabyte Aorus Elite Motherboard. GPU is Aorus 5700XT. Memory is Corsair Vengeance RGB Pro 3600Mhz 32GB.

I seem to have multiple places that I can set fans and overclock:
1) Gigabyte's own App Centre plus SIV (System Info View)
2) AMD Radeon Software
3) AMD Ryzen Master
4) Bios itself

I'm trying to find a simple guide to overclock etc or create fan curves but am having no joy and am wondering if I am missing something? Can I uninstall some of this software etc (the Gigabyte stuff seems a duplicate)?
 
Just set XMP on the RAM to 3600mhz if not already done, then create a custom fan curve in the BIOS. I would also download and use the latest 1USMUS windows power plan and make the required BIOS changes and leave it at that. Personally speaking of course.
 
Hi all,

Just a quick question from me. I'm thinking of purchasing a 3900X but I have a question about what CPU cooler I should go for. I was thinking the Noctua NHD-15. Would that be a good choice?

Thanks.
 
Got a 3900x recently, seems like it's normal for the chip to run 40-50 degrees idle. I have mine under a D15 and run about 700rpm. In Destiny 2 it averages about 65 and in Cinebench R20 peaks at 72.

I have a Dark Rock Pro 4 cooler, and my 3900x runs a bit hotter than that when gaming at 1440p on a superclocked 1080ti - around 72 degrees, but I only have one fan extracting heat out the back of the case (and that air coming out is pretty hot). However it's nowhere near the 95 degree limit, and stable, so I'm not too fussed. Idle temps are roughly equivalent to yours.

Exactly, I think it's quite easy to get focused on low temps when in reality as long as it's within a decent range there's no issues.
 
One thing that is confusing, is Ryzen Master and AI Suite showing very different info. AI Suite is what is used to set fan curve based on temps, so not sure what is what. Ryzen Master shows a lower clock and temp than AI Suite..
