no thanks it was an interesting read and I agree it's a step I never wanted to do delidding, buying a better cooler is one thing, destroying your component to improve it is not something I'm ready to do on a brand new item, build it better ><
I fear you will get limited in your choices of cpus in the future, Intel and AMD are both going in the AIO/custom loop direction, the real "TDP" is only going up so expect 200watts cpus to become normal and at that stage liquid cooling is the only solution, air coolers size-wise can't really become bigger you can only increase fans speed aka noise

but I get it we all have our limits and things we don't want to do (liquid metal is another one for me I use kryonaut) thats why manufacturers sell so many different products

Had a 4790k I got in 2014. Hit 95~100C in seconds of any bench test on stock intel cooler. What a rip-off (knew the cooler was bad going in but gave it a test anyway, wow, how could they get away with this?). Prime95 out-right crashed the system with a BSOD due to motherboard fail-safe procedure in about 5 seconds, if that. Yes, I know you shouldn't run Prime95 on those, I just wanted to see how long it would last. It was at stock settings, stock 4ghz speed... for five seconds TOPS it lasted. Not a good show of a reliable product with company standing firmly behind what they sell. TRASH.
Pig of a chip. Couldn't go over 4.5ghz even with a window AC unit pumping directly into the case, even that didn't turn out to last.
Needed delidding (and a delid tool), liquid metal under and over the IHS.
Needed a 100$ air cooler (okay I spent 20~30$ extra to get one with 'designer colors' having dumped that much into it already) to even run properly and not be throttled below 4ghz stock speed all the time.
After all that, I could run all-core at the 4.4ghz turbo speed. That was it.
Asus Maximus Hero z97 board, 2400mhz cl-11 memory, big case, plenty of fans.
Has I known it was going to be all for nothing, I would have just got a non-K sku and a mainstream basic motherboard.
All that extra money spent and couldn't even upgrade the CPU unless I wanted to spend 350~400$ on a 5775C which wasn't really an 'upgrade' but maybe a few % here or there.
While I will admit for it's time it was no slouch, I'd have rather shaved 250$ off extra costs and gotten still most of the speed boost I originally did.

I had a 4670k with the same heat issue as you and it wasn't a big hassle to fix. Took me around 45 minutes, the same amount of time you took to write this post.


--Combo price 7/2019 for intel and AMD (this is when I had purchased all parts) :
AMD get 50$ off motherboard with qualifying Ryzen 3xxx purchase. This dropped the cheapest x570 Asrock board from 154.99$ to 104.99$
3700x Box CPU 329.99$ motherboard 104.99$ for Asrock x570 Phantom Gaming 4, both new. 434.98$ pre-tax. Stock cooler included free in price as it 'works fine' - still using it, too!
Intel (no discount!) 9900k + Z390 or Z370 motherboard was ball-parked in the range of 489.99$ for the CPU + 150~400$ for motherboard, so at a min/max of 639~889$ USD + Cooler costs of 40~120$ depending on which you got. So that price could be 679$ at the start, ended up ramping up to around 1000$ for board, chip, and cooler!

Now you're just making crap up. I just bought an i7-10700K for $387 and an Asus z490 Prime A for $199 (I could have got an Asrock for $149) before combo discount of $50 off. And any enthusiast who has a PC under 8 years old likely has a cooler thats adequate enough to work since lga1200 is compatible with 1150, 1155, and 1151. All i have to do is bend two new pieces of acrylic to upgrade my loop to work with the new motherboard/chip.



Also not including the costs of a custom loop or any additional case-fans you might need with intel's heat.
I am also not including the cost of an increase of 40~50$ in a bigger power supply you would need for the intel chip.


Have you see the power draw from AMD 3900x when subjected to the exact same torture test? Notice how they dont compare overclocked Ryzen to overclocked comet lake? Only OC to not OC?
This is why:


Yep... 250+ watts from that ryzen CPU that has 105 tdp


So *YES* those of you who built 9900k systems, I HOPE it's faster than this 3700x. For a little less than double to well over double the cost, I hope for your bank balance sake it IS faster.
I just COULD NOT see to spending double for that 'last 3~8%' of speed. Even if it was 15~20% in everything, I would not have budged. After the miserable experience with my 4790k, fast or not, I likely wouldn't have gone intel if the price was equal. This coming from someone who almost always tried to have an intel system when possible - even in the Pentium 4 days (that, that was painful).


The absolute worst thing you can do to convince people to buy AMD is lie. And thats what you're doing.


*SNIP*

i was gonna respond to all of this but i have a life. one last thing though...


So I hope this helps. This is just the typical person buying a Ryzen 3xxx and why I did not pick intel again.

Save that money and spend it on a GPU or a bigger processor or more memory, or a bigger SSD. Try not to go too far beyond one or two paces past the point of diminishing returns, and not any past it if on a tight budget.
I am not entirely sure that I could even look at pricing out a new intel system, until we end up in another AMD FX / Bulldozer era - an era I wish not to remember.
Sorry for the book, but this is the first thing I thought of when delidding comes up. Why should we have to even do that?

And yet.... overclocked temps for Ryzen 3900x are even higher than 9900k overclocked. So many reviews of these new intel chips love to omit the power consumption and temps of the AMD chips.

Couldn't intel have done this, who works there, finally they solder those things again yet still they can't get it right...

I only mentioned overclocking in my disappointment about the 4790k. I never mentioned overclocking a 9900k or a 3700x, as I wished to do neither. Nor did I mention a 3900x, a chip you brought up out of nowhere. I'd rather not get baked out of a room in my new home that has central AC - AGAIN (as happened with the 4790k, made this the hottest room in the whole house). I don't have time to mess with "water features" or overclocking on a production system, I just want to use it, not play administrator when I could be being productive here or even enjoying a game now and then.
Prices listed were from 7/2019 when I built the system - I did have that listed. Everyone else saw it; however, in your building of a hasty rushed defense, you must have missed that. It's okay this time, I understand. Please read more carefully next time to avoid that.
But thanks for calling me a liar, I love it! Please keep up the name-calling enough so everyone else can see how maturely you conduct yourself. I just hope I am not kicked out of here before I get to see the results of you trying to blame the resultant storm on everyone but yourself.
I am just glad I found a good deal when I did - and it sounds like you found a good deal, too. Everyone wins, normally... for most folks anyways.
I just hope your system is faster than a stock 3700x with a stock cooler is, with all the extra money poured into cooling that was spent.
Have a peachy day sugar, and thank-you oh-so-much dearie for selecting (out of all the people on the internet) ME, I feel so SPECIAL now just because of you! You've made my day - Thank-you!

P.S. Please write back soon, so I can be entertained for the next 45 minutes (by your watch) spending it writing back to such a nice wholesome person such as yourself... Thank goodness THIS post only took me 44.65536 minutes to write.
My apologies in advance to the rest of the forum users, but someone from WCCFTech must have got lost / taken a wrong turn, heh heh.

Why? Why can't people at least read text? Measurement is on wall socket. Then you have idle power draw right next to it.
Non-OC 3900X has idle to load difference of 123W. That's after PSU efficiency and VRMs efficiency on MB. Actual idle to load difference on CPU itself would be maybe 105W. (Very power efficient PSU/VRMs. Practically more of energy would be wasted on VRMs and therefore expected difference in CPU would be like 85~90W.)
So, statement like: "Yep... 250+ watts from that ryzen CPU that has 105 tdp"
Looks like intentional misleading.

Then graph itself shows quite high idle power draw in comparison to other CPU/MB combinations. I can't replicate such high idle power draw.

And then there is that intel i9-9900K 95W (intel's TDP) system which idles at 51W and fully loaded has 228W. That's 177W difference and if we count in PSU/VRMs power efficiency, CPU itself may account for 150W of that change.

So, what's bigger offender?
R9 3900X with AMD's TDP of 105W which actually adds around 105W from idle to load on weirdly power inefficient MB.
Or i9-9900K with intel's TDP of 95W which easily adds 150W from idle to load on very power efficient MB?

As far as 3900X temperatures go. Maybe you should look at what is under IHS and how are today's heatpipes for air cooling placed over those parts. And through what places liquid flows in liquid cooling CPU block.

I got my liquid cooling for this specific reason. Because CPU block can be rotated around at quite a few angles and I can pick best one.

Worst case scenario is when someone buys air cooling and just one heatpipe goes above both CCD chiplets because it can't be rotated by 90°.
