I start with cooling a 4090 (original air cooling, then water). The key variable I am interested in post is the delta between GPU and Hotspot. This parameter can be quite telling, also if it deteriorates over time when running the same app and oc. More to come later, and your comments are welcome. 4090 clocks shown with core voltages (1.00, 1.05, 1.075, 1.10) range from 2775 MHz to 3240 MHz, PL up to 650W. Apart from keeping overall temps in check for a 600W + power limit (even if one usually sets it well below that), it is also a question of keeping the temp delta between GPU and hotspot relatively low - typically less than 20 degrees delta for a water-cooled GPU. Another parameter to watch out for with the newer power hungry GPUs is how long 'heat soak' can be delayed....the bigger the cooling surface of the rads, the liquid volume in a loop and also the number (and type) of fans, the longer heat soak can be delayed. The 4090 system above has a total rad space area of 1320 mm x 63mm 'triple core' copper / brass rads. Below is a comparison between a single core aluminum 360 AIO rad and a triple-core copper/brass rad. One guess which one cools better... When it gets to cooling modern GPUs with gobs of power, the GPU itself (rather than just rads, pumps etc) need attention. Obviously, there is the water-block itself, but also the thermal paste for the die - I typically use Gelid GC Extreme for CPU and GPU dies, but there are other good pastes out there. For VRAM, I have switched to thermal putty a while back and so far, the experience has been great - even after 2.5 years plus, identical temps show in stress tests at the same adjusted ambient temp. The only really draw-back of thermal putty is that it is a bit messy to clean up - but I rarely take a GPU apart after water-blocking it; I have some water-blocked cards in regular use for more than four years without disassembly. For VRM components, I also either use thermal putty, or Thermalright thermal pads. Finally, I add thermal putty to the back of the GPU and then mount an extra heat-sink on the back - it does help with power-hungry GPUs that generate a lot of heat over a small area.

Hello GPU aficionados I am starting this thread to look at modern GPUs and some of the things to look out for with cooling, power and also mounting... Given the various 12VHPWR issues which have crept up, as well as 'cracked' PCBs and such, I figured a closer look is warranted...

That new Threadripper looks yummy - even though it '''only''' has 8 channel DDR5, instead of the 12 channels the new Epycs carry But if you can't wait, how about...

What is amazing is that these are regular Zen4 cores (just binned) but with ludicrously low power consumption. Being regular cores means no funny stuff with scheduling et al. So yeah, 32 core Ryzen laptops are a real possibility. Personally, I like to settle at a slightly different config: A nice 32 core oc-able Threadripper Pro w/ VCache and 12-channel DDR5 'desktop'

@bonami2 ...very interesting ! I better start picking the parts for an AM5 platform beast of burden

...yeah, probably one of these chaps (YT time-stamp) gets some extreme cooling going for one the new monsta CPUs...

Well, these will definitely play solitaire really well. @bonami2 will get me two of each

...an interesting if lengthy video referencing not only some of the AI APU/GPUs but also points to the real challenge for anybody but NVidia - the software ecosystem. But never say never...

...and some more of that

...yeah - FS 2020 is a lot of fun, even more so with a decent 4K GPU. I like it because I can use an electric Volocopter for 'low and slow', do some stunt flying over our neighborhood in a Pitts Special, pilot an Airbus A320 over Northern BC - or choose something a bit faster Ranked by speed: ...34 KT ...121 KT ...~ 309 KT ... Mach 1.46 --- inverted Mach 3.79...

some speed junky fun...

...not sure what to call this genre, but it also has some nifty Dolby Vision and Dolby Atmos in. Enjoy...

...more future graphic tech updates, including Unreal 5.+ ...some of it really looks unreal

these vids compliment OLED visuals with Dolby sound variants... ...& some more OLED eye-candy ...speaking of eye candy, some CP2077 4K path-tracing and FS 2020 from earlier this evening, looks great on OLED

Microsoft *might* offer FS 2024 as an upgrade (for mucho $s) for FS2020, but at least there is a lot of carry-over in addition to the new stuff. I currently have FS 2020 on two separate systems in different rooms (one with a 3090, the other with a 4090). If FS2024 is more than *an upgrade*, I probably will just add FS2024 on the 4090 and leave the FS 2020 on the other setup as is, at least until all the bugs are ironed out. FS2020 took a long time and a gazillion patches to become the super-smooth DX12 DLSS (2)3 it now is .

...I got the premium deluxe version on day one. By and large, @Andrew 's comment above makes sense though; still, I prefer some of the rarer models that are included with the top version. Re. controller, I use both the X-box controller and the Logitech Extreme3D Pro simultaneously - more than enough control, IMO.

...speaking of A380s...'hanging about' in the summer heat at the Geneva airport in the Volocopter and watch A380s and other models take off, land and taxi. Looks even better at night ! 4K png original; check in full size EDIT @Andrew Kennedy Airport... 4090 gaming stats

some Volocoptering (high and low) above Tokyo

Monday morning...and in the middle of being hyper-busy with an AI project, my main work machine started to give me some odd messages when working on some graphs for the project : ...ok, so checking out that provided link : I tend to run the second most-recent driver package for the AMD Radeon and 'never' set it to auto-driver updates, given the observed issues with brand-new AMD drivers. Alas, once I updated the Radeon driver to the latest version this morning (fingers crossed), AMD Adrenalin software was back and working fine... ...however, now my 'Print_Screen' button automatically engages the Microsoft snipping tool (I had another software set as default); Print_Screen doesn't work anymore on any other programs UNTIL I have first used the MS Snip tool for a given image (only then can I use the other programs)...and of course Microsoft Edge displaced Firefox as the default web page program. These are just the first few observations of Microsoft's latest 'patches' as I am too busy work-wise to check everything else. That said, we have started to move more and more office machines away from Microsoft to Linux - especially those dealing with code, documents, emails and such. Microsoft's latest AI-enabled patch is yet another (in my opinion) illegal push into the privacy and secure document and communications zone on a PC...no thank you. Also, we have a strict policy to NOT use OneDrive, yet some of the email contents have disappeared with 'a link to server to view'... With AI being all the rage and Microsoft's heavy investments into OpenAI / ChatGPT, I expected even more snooping and 'appropriation' would be going on, not only on text files and emails, but also graphics and audio, given AI's voracious training data input demands. Fortunately, my other system (below right is Win 10 Pro) instead of the main work system (below left, Win 11 Pro), though Microsoft is sure to backfill Win 10 Proa as well, IMO. So yeah, major systems here are already being re-vamped for Linux; we'll keep a few on Win 11 Pro - but not for docs, emails and such.

...the real thing / A380 - enjoy !

...had a chance to thoroughly check at a 65 inch LG G3 w/MLA recently...wow. We don't need a new tv / monitor just yet, but when the time comes, a big LG MLA OLED is on top of the menu. Meanwhile, some more new eye candy for all you diehard OLED / Dolby fans...

...can't quite tell the fan air flow direction (looks like blowing inwards towards the socket though)... fyi, some XOCers like the two helper fans turned around so that they help evacuate potentially moist air away from the socket and surrounding electrical bits...in my personal experience though, it doesn't make a ton of difference

...light evening snack of tuna w/sesame sauce, blueberries and some rye bread on the side
