I just bought ryzen 1700 anyone else going fanless? No OC

The ryzen 1700 non x has a tdp of 65 watts and im sure can be cooled passively if not overclocking. Its just a matter of adaptors. ive had a zero db system with a amd 5350 for quite a while now and really like the quiet. And have run a intel g3220 (54w tdp) passive with a hyper 212 evo heatsink. As long as your not encoding it works. Both of the systems are in open air no case.
Hmm, I didn't know you could get away with just using passive cooling methods, I guess times are changing. But I think it also depends on what you are doing, if youre gaming with everything at max then I doubt passive cooling will keep your system stable.
And you're really running your computer without a case? lol
Yeah I was going to say you wouldnt go passive in gaming with the g3220 but there are coolers i could buy and run passive im sure that would allow it. And yup no case you can mount it to a small sheet of wood.
But my 5350 is literally on some screws and nuts on my desk with a 12v laptop type power brick on the floor using a am1h-itx motherboard and the ARCTIC COOLING Alpine M1 Passive cooler and two ssd hard drives using on board video and a stick of 4 gb 1600 memory.
oh I decided im going to use the evga 500 power supply i have for the ryzen build since I had the power supply all but right beside me and I couldnt hear the fan. I like their power supplies because they are single rail supplies and cheap.
ps...Ive actually used it to video encode long hours a few times and temps were fine. You could go to sleep in the same room and not hear anything from the pc. Haha

I also want a system with less failure points and passive vs non passive I doubt you will find one as cheap that would still work if the fan went out plus a fan pulls in dust. To go completely fanless with a pc case they should make an actual tower case and use the fact that heat rises to exit the heat naturally. You could build one from wood just wide enough for the parts if you wanted one that did that non commercial. (Ive been considering doing it for the last two years now)

@MaDDD ... i don't think it's a matter of why you would want to do it as much as it's a matter of can you do it ... LOL
Interesting idea Sean. I'd love to hear how you make out.
What would be ideal would be if there was a way to use the steel or aluminium case itself to dissipate heat.

Actually I think I just got a good start on the idea. Use a large perpendicular fin heatsink and then place a riser of the same material so that you get enough height over the other motherboard components and the rest would be easy. I actually already have a 16x 7 or so heatsink with large fins. It's overkill but would work haha. I got it to make a high powered home amp.

Good luck passively cooling an 8 core 16 threaded chip mate.
While it may have a 65w tdp spec amd have always interpreted their tdp figures differently to intel.
The 95w ryzens have been shown clearly to pull up to 140w under maximum stress & they run HOT!

Why am I not surprised? AMD is known for their processors to run hot. Although I still have an old Athlon X2 lying around here, which was bought when I didn't know anything about processors. Intel > AMD anyday, but at least AMD is getting better!

^ to be fair it runs cooler & uses the equivalent power of its Intel counterpart.
Bear in mind what these chips are 8 core/16 threaded - essentially double the performance of an fx 8 core but with similar load temps & half the tdp.
They don't run hot 'because' they're amd - they run hot because you're essentially getting double the performance of anything that amd have previously had on the market.
Fully expect even the 65w tdp rated to pull 100w or so at full pelt.
Of course you could down clock or limit its performance to allow passive cooling but then why would you be spending that kind of money on a high performance CPU just to cripple it for the sake of fan noise??

Hmm, I am actually impressed that AMD is pulling that one off (8 core/16 threads)haven't seen a Intel chip capable of that yet. Even their 7920HQ don't seem to that pull that off. I'm sure they'll release something similar that's cooler.
ill be right back with something for you....."Amd ryzen 7 1700 total system power idle and load 49 (idle)
132 (load)" Thats total system power and they arent the only one with those results. Gamers nexus on youtube did as well. 133 (load) and 58 at (idle) This is total system power.

Dissecting the info I see now what your talking about. (problem solved see next post)
It looks like they will have a am4 bracket for my deep cool lucifer v2 early may. That should work passively.

I was going to use it on my 4930k I had yet to assemble but now im selling it and the ryzen is taking its place. it is 45% better at multi core which is what I want. And less watts since the 4930k is 130 watt tdp.

I wouldn't call it "TDP", which is thermal design power. Better to just say power consumption.
Just to give a point of reference, my older Core i5, which has a 77w TDP, has a total system power consumption at the wall of around 33 watts at idle and, under an AVX load a total system power consumption is ~82w. Subtraction gives us a difference between idle and load of 49w, with actual power consumption of the CPU under load probably falling somewhere between 50 and 60 watts (at the wall). My power supply is something like 88% efficient so you can subtract maybe 6-7w from that to see how much electricity the CPU is actually drawing and turning into heat before conversion losses.
49 idle seems pretty high on Ryzen, especially considering it's built on a much newer and lower power process than my i5, but maybe AMD hasn't sorted out their power saving features yet. 132 - 49 is a difference if 83w, which is a good deal higher than the 65w TDP the chip is rated for, but it's hard to have a clear idea of just what is going on without a lot more information.
Regarding passive cooling, I don't see much point. If you're still going to have a fan on your video card or power supply, or have spinning disks for storage making noise, pulling a fan off of the CPU is kindof pointless. And besides, the cooling ability of a heatsink with a fan spinning and a very leisurely and effectively silent 500rpm will be very significantly higher than one with no fan on it at all. It's probably best to get a few high quality fans (e.g. Noctuas, which have almost no bearing noise) and spin them very slowly.

I have a gtx 1060 6gb I havent used it yet but it has the fan stop feature so it doesnt come on until a 60c temperature. It gives me something to work with for additional silent cooling ideas. Im not going to give up yet haha.
I decided im going to use the evga 500 power supply i have for the ryzen build since I had the power supply all but right beside me and I couldnt hear the fan. And my hard drives will both be solid states.
And i may run this without a case until I decided what I want to do there. So as of now its more or less completely silent if I solve the fans on the gpu. (problem solved see the 6th post down)

Duhh bud haha. I was commenting on how it was easy to disassemble for after market cooling. Its just four easy screws after that to separate the heatsink. I just ordered a Accelero S3 passive cooler. Their website says gtx 1060. It was 39.99 plus tax. It cooled a rx 470 5 degrees cooler the stock fans so im good.
