Well I like the Thermalright Silver Arrow SB E Extreme, but hate those dam red fans, noisy when above 1200 rpm. so I was looking at replacement fans and came across these baby's! Prolimatech Ultra Sleek Vortex Fan - 140mm now these are silent at max 1000 rpm and move 98cfm 18dba I know the thermalright TY-143 140mm can move 130-cfm but at 45dba

so I went from this



to this


and iam enjoying silent 98cfm, plus they are black, and offer greater space between first CPU cooler fan and the back of the top GTX-680 :)
 
The temps are the same, even at full flight the thermalright fans at 80% to 100% made no difference, but these offer the same temps but silent at full speed. plus the better air gap from the back of the top GFX card allows better air flow to the first fan, so my temps are the same.

a great upgrade for silent air cooling!
 
If running over 80% made no difference, could you not have just run the existing fans slower

well you can run the existing fans slower but they don't move 98cfm like the new ones do silent, 1000 to 1200 rpm and you can hear the old fans and that's half speed.

plus the air gap is better with the new fans!
 
Part of the problem is the orientation of the heat sink, you're sucking hot air from your GPU so that compromises the cooling ability of the fans and heat sink, because the new fans are narrower they at least have some breathing space. I would have thought the original fans would have performed a lot better if you had the heat sink rotated 90º anti-clockwise with the fans pulling air from the front and blowing out the back of your case.

That made no difference to how cool the cpu ran either way round at idle, infact at the top of my case I have 2 X 120mm fans sucking air directly above cpu cooler and as hot air rises its perfect! at load its cooler this way round than pushing air toward the back of the case. The GPU's have reference design coolers that expel heat out the back of the case anyway so no heat rises from GFX cards.

I agree, I had mine in both orientations and from bottom to top was slightly better even with the minimal clearance space between GPU and fan.
 
Prolimatech Ultra Sleek Vortex 14 test 59cfm@900rpm & 70.9cfm@1140rpm.. 140rpm faster than Prolimatech spec.. probably about 64cfm@1000rpm; about 2/3 of spec. which is very good for a thin fan. Would be interesting to know what kind of static pressure rating the have.

As for the TY-143's being loud.. being so close to your gpu it doesn't surprise me. 140mm fan needs at least 40mm of clearance to draw air into fan.. and as close as it was to your GPU it sure didn't have that.

I'm running TY-143's on both a Silver Arrow SB-E and a Phanteks TC14PE. Both are silent at 700rpm and can hear air moving through cooler at 1100rpm.. just loud enough to know they are running up from 2m away.
 
I was considering getting a Silver Arrow SB-E, but if it's unbearably loud I might as well just get a Phanteks PH-TC14PE.

The temp difference shouldn't be too big anyway.

With the high end air coolers, go for the looks. They all perform within 1-3'c of each other and that's nothing when you take into consideration ambient temps etc.

Personally the SB-E gets my vote, it's just a mean looking cooler :D

Exactly what I have found, it seems the cooler likes facing upward!

I tried the silver arrow SB extreme the other way round where fans were not close to my GPU and still found them noisy above 1200 rpm which isn't half speed. these new fans keep my CPU just as cool but with no noise like a jet aircraft takeing off once they get to 1100 rpm unlike the standard fans at 1600 rpm sound. my case sits next to me about 2 feet away, proberly might be better 2 meters away under my desk but no point having a window case then.

I think these new fans work well and the cpu cooler facing upward offers better cooling this way.
 
The fans on the Phanteks are too loud for me at the max of 1200rpm. Droping them down to 1000rpm takes the edge of the noise and still gives great cooling.

I don't know if it's possible for you to try moving the fans up 1 so the fans are in effect pulling the air through the fins. This was you leave enough clearance between GPU and heatsink. This is the way I have mine.

Horizontal or vertical really makes no differnce to cooler but how well the hot exhaust exits your case will make a big difference in case temp; which translates to CPU temp.

Try your new fan by just starting mounting screws, setting them on desk top and running fan full speed. My guess is it will be louder than if you have it 30-40mm above surface. The restricted airflow to fan causes fan to be louder. ;)

Standard Silver Arrow SB-E fans top speeds are 1300rpm for TY-141 & 146 and 1100rpm for TY-150. These are variable speed fans and when used as designed are not loud at all. You chose to buy lower airflow 1000rpm fans instead of adjusting your PWM fan curve to keep them below 1000-1100rpm because they are too loud above that speed and post that the TY-143 are too loud.

Your new fans are nice fans. My point was/is that the TY-143 will move as much air at less rpm than your new fans and be just as quiet. With both of systems running 1000rpm I have to concentrate to hear them.. The sound of heating radiators in the room is louder than than 4 TY-143's running at into coolers... as is a good rain on side of double block wall of house.


Edit: What wam7 said. There is very little difference in temp pull air through cooler vs pushing.. maybe 1c at most. Easy to try and might make it even quieter.

well I have 2 x 120mm that exhausts any warm air directly above the cooler. so no problems there.

The whole thing was that the CPU cooler works better this way round cooling wise and I can use 41mm height ram without interference from the cooler itself, infact you can use 55mm high ram this way round, plus no fans sitting on top of ram. as for adjusting fan curve I did adjust it so the original fans ran at a max of 1200rpm, not to loud. but in a push pull config cooling wasn't as good, even with the closeness of the first fan to my GPU that config offered better cooling even at lower fan speeds. So what I wanted was quiet fans, pushing enough air to keep the system cool but also offering a better air gap from the GPU to cooler, also giving me very good ram clearance from the cooler itself. that's why I purchased these fans and so far the cooling is just as good as 1200rpm standard fans, but totally silent. and I have a better air gap to top GPU card.

The second thing that ive noticed is that now the 2nd fan in the middle of the CPU cooler also has an air gap unlike the original fan which relies on air passed through the fins of the cooler from the first fan, the airflow from top of cooler to case exhaust fans is greater, as the middle standard fan was restricted in air as it can only draw on air passed through the fins from the first fan which starved it of air anyway. as you said a fan needs 40mm clear to be able to breath properly.

so far these thin vortex fans are working really well, with better air gap to GPU card and improved air gap in middle of cooler. I feel these are better than the standard fans for noiseless operation.
 
Definitely better the way you have it setup. They are nice fans.

I think if you used the TY-143's in pull/pull middle and top of cooler and adjusted the fan curve so they maxed at 1000rpm at whatever temp your CPU runs at under load they would be as quiet. I'm using Gigabyte motherboards and set ET6 PWM for 660-700rpm idle @ 24-27c and 950-1000rpm full load @ 43-47c.. that's 1 session rendering graphics; 2 sessions rendering at same time is 1050-1100rpm@45-50c; ambient is 21-21.5c Think the ET6 settings are 30%@30c and 100%@60c. If I unplug all fans runnign single session CPU max's at 70c after about 30 minutes.. and when I plug fan back in they spin to 1500rpm for about a 45 seconds than slowly drop back to 1000rpm over next couple of minutes. I have no exhaust fans but 3 TY-140 intakes front and bottom that are PWM controlled by CPU fan PWM signal.. so they idle about 25rpm faster than TY-143's on cooler and when TY-143's are 950-1000rpm they are 900-950rpm. Fan speed varies some depending oh how much dust the filters have in them.. the dirtier they are the slower the fan.. maybe 50rpm loss at most. I usually hoover them every other week when I do the room. ;)

I think the Ultra Sleek Vortex 14 are a very nice fan and do very well for a 15mm thick fan. Thanks for telling us about them. Might need a thin fan someday.
