LOLOL....

San Ace Whoreage... 8 to be exact.

I had the same idea you had... lets have some fun with a LOT and LOT of San Aces + other fans...

It ended up like this... 16 fans...

Holy guacamole.

I was laughed at even on XS for making something that massive... :sneaky:

Oh sure, they're laughing NOW . . . when it comes for them in the middle of the night, they won't be laughing.

But id push the GT.
Its quiet.. very durable.. and also they perform extremely well on a sink or radiator.

It's still in consideration. I already have the 45 dba 120x25 Delta shipping for the center fan, and there's a 44dba 120x38 Delta that looks nice for the pull position, but I haven't pulled the trigger on it yet (also considering a Panaflo H1BX or a San Ace 1011/modded 101). The push spot is blocked by RAM, so if I do get a GT, it's probably going to go into the center position and cede the pull position to the 45 dba Delta PWM fan that's already shipping.

It all really depends on how bad this FM-121 really is noise-wise. It was advertised as 39.7 dba, but that was a joke when it was new, and 3 years later, it hasn't gotten any better. More like 50 dba (not measured, but damn is it loud). Once the 45dba fan arrives, I'm going to toy with it and see how loud it is in comparison (and how much more noise I can tolerate on top of that).

Talk about a waste of fans...

:eek:

Art is subjective. However, if you're not careful, it would be a waste of fingers rather than a waste of fans.

I have a Panaflo medium. On my Megatron at 4GHz, it gave me 51.5c over ambient at 2080 rpm. I measured the equivalent of 37 dBA SPL (some reflected sound from the vane stack, I think). The specs are 86.5 CFM @ 2100 RPM, 35.5 dBA.

A roughly equivalent San Ace is the 9G1212M101: 1950 rpm, 74 cfm, 32 dBA specs. I got 52c over ambient, 1960 rpm, 35.5 dBA.

OTOH, the San Ace -H101's gave me 50c over ambient in 3 runs on two fans, with noise at 38.5 to 40.5 dBA equivalent, measured as mounted on the heatsink (some reflected sound from the vane stack, I think). This is nominally a 99cfm fan, 2600 rpm (mine run at 2500) and 39 dBA.

I imagine that the Panaflo high specs of 103.8 CFM at 2500 RPM and 41.5 dBA are accurate. So, you pays your money and you takes your chances.

Yep, that's Sanyo Denki quality for you. Seems like airflow is making a bigger difference on the Megahalems than static pressure. I checked the medium Panaflo specs and the static pressure numbers were okay, but somewhat underwhelming when compared to the high-speed. That being said, the H1BX had lower static pressure than the H101s/H1011s despite the higher airflow (and higher noise), which is why I'm not totally sold on it.

I imagine that the Panaflo high specs of 103.8 CFM at 2500 RPM and 41.5 dBA are accurate. So, you pays your money and you takes your chances.

That's what I'm hoping for. The other one I was looking at is this:

http://www.sidewindercomputers.com/deaf12rechis.html

With that fan I would get higher airflow and higher static pressure than that of an H101/H1011, and I think it would make a pretty good complement to the PWM Delta I already have on the way. Sadly, it is not a PWM fan itself, so I would have to get a separate fan controller to tame it if 44dba proves to be too loud (and there goes all that airflow and static pressure). Still, if this FM-121 is as noisy as I think it is, both Deltas would probably fit within the same noise profile at full tilt.

On a serious note: update! Got the PWM fan harness and 45 dba Delta PWM fan installed.

Downside: when the PWM connector is plugged into the 4-pin CPU fan header on the mobo, the Delta wants to run at near-0 rpm. I never let it get past BIOS because of that, so I may need to let it heat up before the fan will engage. However, I set the minimum fan speed to 87.5% in BIOS and it still chugged along at a snail's pace. I don't know how many RPM it was, but it was pretty sad. My CPU fan header may be screwed up which might explain why the Noctua 140mm fan was spinning so slowly.

Upside: without the PWM connector attached to the CPU fan header, the fan runs at 100% all the time, and it isn't much louder than the Silverstone FM-121 I removed. In fact, this one fan, when positioned as the center fan on my nh-d14, moves enough air to replace both stock fans and the FM-121 exhaust. All I had to do was use my mini wire cutters to cut out the fan grill as per ehume's recommendations and now my HSF is doing double duty.

With my old fan setup, getting this chip Prime95 Blend stable @ 3.7/NB 2850 required around 1.5v vcore with load temps of 49-52c depending on ambients.

With my new setup, I have it prime95 blend stable at the same speeds with 1.44v vcore and a load temp of 45c currently. Ambient has been creeping up on me today (AC is off) but it's still cooling like a champ. Gonna try pushing voltage down lower to see what will work.

Since the 45dba Delta is quite tolerable at full tilt, I have ordered a Panaflo H1BX and will be applying some Liquid Metal Ultra once it ships in from Ireland . . . um . . . whenever it gets here.

Stupid volcano.

Try the Noctua clips. But if they don't work, 38mm Megahalems clips should work.

On PWM fans: sometimes you have to get past BIOS for them to kick in. Given that you're using a D14, your passive cooling should let you run on idle at least thought OS start. If your fans don't kick in, see if there is an advanced setting in your fan control software. With ET6 there is an Advanced mode that lets me set a minimum speed for a PWM fan.

Congrats on your bravery in cutting out the grill. That's one less fan you have making noise.

Hmm, good idea. I didn't know the Megahalems had clips specific for 38mm fans.

The main reason why I went with the H1BX was that it appears to have nothing that would stop me from using the Noctua clips, unlike the 44dba Delta I was thinking about using which has these seemingly-unnecessary plastic bits jutting out on either side of the mounting holes. At least this way I have an excuse to make less noise.

I'll hook the PWM connector up to the CPU header again and see if things start working once I get past the BIOS. The nh-d14 did a better job cooling with negligible fan speed than the stock cooler that came with my chip (with fan at full speed). So sad.

The grate was surprisingly flimsy, and retiring the FM-121 was worth it.

Okayyy, got my H1BX (finally, stupid postal service), and while it looks like my Noctua fan clips will work, the fan clip pegs are too short. The mounting holes are so thick that they don't go all the way through.

Anyone know where I can get some pegs that are longer that'll work with a Panaflo/NMB-MAT H1BX? Or do I just go for the zip ties?

Paper clip + needle nose pliers. When you fail, make another. And another. Eventually you make some that work..

And you may need a side cutter to trim the excess paper clips.

Use wire ties. I abhor those metal clips. The fan WILL fall off sooner than later. If the clip falls into a running system or on the back of the GPU pcb... :eek:
