Noctua makes some 80mm fans that are decently quiet in my experience (as long as they aren’t running at 100% ofc). Looking at pcpartpicker they also have some 92mm fans that I haven’t personally tried, but I would expect them to be pretty quiet too.

yeah i have nothing but love for noctua, all fans in all my rigs are noctua!

still tough, noc's don't exactly come cheap.

alright boys, i'm gonna need some advice on my Folding server. brace for a wall of text.

here's the deal:

Looks like the res is blocking airflow through the rad, and it would also act as an air deflector if so, to push some air back up towards the top of the case.  It doesn't look like it, but if there's enough room to have the res next to the rad rather than in front or behind it, or even just lengthwise instead of across it, that would probably help.

Try the 92mm redux. They’re a little less expensive but are only 1600rpm versus 2000 of the NF-A9 with a slightly lower static pressure which shouldn’t be as much of an issue for exhaust. I have both models and while louder than the 120s they’re not too bad

i honestly don't think that's the case. the res is a lot more narrow than the radiator, and i have systems that are a lot more constricted on the radiators that still have plenty of room for air to pass through, like the system in the spoiler below.

Spoiler

keep in mind the temps where worse with my previous pump/res layout, which wasn't blocking the rad at all for the most part.

Spoiler

as for the air deflecting part, that seems to be pretty plausible. and that would explain why my temps improved when i blocked the path above the radiator with some cardboard.

seems like this would be the best option then. kinda sad they don't have these in black, tough grey isn't that much worse.

so what do you guys think? should i seal off the rad area from the rest of the case? get more fans but potentially more noise? any insights are appreciated!

Noctua 80mm fans in the back as exhaust. That should help out quite a bit, because otherwise you're relying on the RAD fans to overcome the static pressure of the radiators AND have enough pressure to pull fresh air in from the front and push it out the rear (from the very front of the case mind you)

It's in a server case! This is one of the least applicable application where color matters

Speaking of which, a few days ago I came back to my main PC and noticed the mouse was lagging all over the place. I knew this symptom all too well....

 

My PC must have rebooted overnight, and the F@H client just started folding. 

 

Once I'm paying for my own electricity, I'll probably set this to fold when not in use, but otherwise I gotta keep the 1080ti off even though those PPD's are sexy.

[RollinLower]

why didn't anybody tell me these are magnetic!  

[GOTSpectrum]

My GTX 1080 slot failed overnight  

 

[RollinLower]

alright, so two redux 92mm fans in the back got me down to a steady 65 on the GPU's while the whole system is under load. that's BOINC on the CPU's and F@H on the GPU's.

i'm pretty happy with that considering the whole system is still quiet enough that you don't actually hear it if you're not standing right next to it!

sliding it out on the rails and removing the top panel still bring temps down another 7 degrees tough, down to 58. i guess i'm just going to have to take that for what it is. 

[RollinLower]

i got it down to 60/61 C now after putting the piece of cardboard back on top of the rad, effectively separating the radiator area from the PC area so no hot air can loop back into the radiators.

that's just 2-3 degrees hotter vs side panel off! definitely good enough i'd say

Well the guy who came to repair the wood around the front door decided he would cut the ethernet cable that ran there without asking if it was used for something, frankenfolder has been out of action for around 30 hours... damn  New cable ran and its all back up and running now though.

what a dick. hope next time he cuts a random cable he gets elektrocuted

Not only that but it runs up three floors, so its a bitch to sort out too

[RollinLower]

yep, 9 hours of downtime across all systems will do that to ya

it is stationed right in a rack in the middle of my living room, and i don't think the girlfriend will appreciate the added noise of more fans. this is the reason i went with watercooling in the first place, to quiet it down.

if i add more fans the only mounting options i have left is 92mm, and if i go for small fans i'm afraid they'll get pretty loud pretty quick.

Put a couple of these Delta wind turbines in it. Wait until she complains then “fix” it with the Noctuas

Looks like my 'hourly' production rate... Even though it's every few hours.

[sazrocks]

What kind of PPD can one expect from a 3900x? I recently swapped out my 6700k for one and 12 threads cpu folding initially gave it 50k PPD, but I had to shut it off because the stock cooler is inadequate. Is it realistic to expect ~100k for the whole CPU?

[RollinLower]

sadly there's a heat wave coming through the Netherlands right now, so i'm only folding on the server for now. this means my PPD is dropping to only about 500K for the coming days.

sadface.

Is anyone else getting slammed by the 11719 WU's?

 

I've taken a hit of at least 30%.

My 1660 Ti runs those around 745-755kPPD. Had about 5 in the last week.

 

In the last week:

 

11718  x5 638kPPD

14180  x2 724kPPD

14158  x3 742kPPD

11719  x3 746kPPD

11728  x1 767kPPD

11726  x4 755kPPD

11719  x2 756kPPD

That's really strange. Mine was dipping massively with those, then bouncing back to roughly 670k-ish (not OC'd) for pretty much all other WU's.

[RollinLower]

now i'm gonna go break the rules a little bit and ask about BOINC in the folding thread, bear with me.

 

there is someone i know that's selling two E5 2650L V2 chips for cheap. those are 10 cores at 1.7Ghz. so lots of slow cores.

right now i am running two 6 cores at 3Ghz. 

would it be a upgrade for BOINC if i went with the 10 cores? or would i be better off going for something faster?

Well, I'm new to folding@home and I was looking through the logs in the advanced control menu and an error kept coming up: 02:37:19:ERROR:Receive error: 10053: An established connection was aborted by the software in your host machine. I'm not sure what connection was stopped and what software would be stopping it so if anyone has an idea please let me know, just for curiosity sake.

Google that error message appending site:foldingform.org and you should find a thread dealing with that.
