Aaargh! Eheim 1048 pump is LOUD - Page 2

V12|V12 · 07-16-2002, 06:23 PM

Okay, I Agree with the bad pump issue... I've got the SAME problem, stemming from this HORID MONSTER ViaAqua 1300! I've got it on bubble wrap and the only reason my case resonates is b/c one of the tubes is touching the side... but still the pump is a strong one, but it shouldn't be making that much damn noise, even on bubble wrap I have under it... What should or can I do, IF in deed I have a bad pump, cause it pumps fine.

I've got a mix of tubing primarily 1/2" lines from pump, block and massive 3/4" lines to rad. Another 1/2" from Rad...

ViaAqua is a loud pump

and most people don't know this but it is really designed to be submerged.

Mkosem uses a via and he says it's very quiet.

Did you fix the impeller? Can one do that on a Via?

awesterink · 07-16-2002, 08:57 PM

I glued the impeller onto the shaft, but alas, no difference. If I take the impeller and shaft out and plug the pump into an outlet, it just makes a very faint hum like any other electrical device with some sort of coiling in it. Perfectly acceptable. But with the impeller and shaft in place (no water), it is quite noisy.

I just can't believe this pump would be bad. Except for the magnet and impeller there are no moving parts, so would it be a tolerance thing? I doubt it. Either it is backpressure, or this pump works perfectly fine and my expectations for quietness are too high.

gmat · 07-17-2002, 02:58 AM

Sir, you've got a bent shaft, sir.
Just go out and buy another one.
The 1048 is really silent and should make the SAME noise when alone or connected to a circuit.

g.l.amour · 07-17-2002, 06:37 AM

i now have 2 rads in series, about 60cm height between all components. 3/8" fittings. so one can assume i got loads of backpressure for a 1048. after the glueing trick it works completely silent again. you'd have to lay your ear against the case to even hear the faint hum when the pc is not started. once the hard disks have spun up, no way to hear it.

judging the amount of crap tomshardware hooks up on the lightest eheim (cpu, gpu, chip, hddcooler, radiator, flowmeter...) i consider it as gmat says higly unlikely that your eheim 1048 is not up to the task of pumping around your water. since pc shops are not the most suitable to test your pump, you might want to goto an aquarium store, and have it checked there.

Hallis · 07-17-2002, 07:36 AM

Could try a TC-4 rev2 :-) i have an eheim 1048 on its way to me ,, i hope it isnt loud enough to be heard over my 1.6a delta fans on 12v

awesterink · 07-17-2002, 08:46 AM

gmat, glamour: worth a try. Hopefully there's some sort of warranty thing here :-)

Thx.

I'd take Tom's articles with a grain of salt... He really isn't on top of this whole cooling stuff, we even discussed that!

We've already established that a higher flow is better, and I seriously doubt that a 1048 can feed all that without sacrificing some cooling performance.

It will work though, but probably wont be as efficient as it could be, with a more powerfull pump.

In short, most people here achieve an effective flow rate less than 100 gph. A few have more than 100 gph. I'm shooting for 200.

g.l.amour · 07-17-2002, 09:13 AM

He is not even using an 1048, it is an 1046. anyway, i think innovatek is shoving some money towards him, the only stuff he ever talks about is innovatek and koolance.
if overclockers.com is a good reference, they state the innovatek to have a c/w rating of 0.23; koolance 0.29. i calculated my cpu xp1500 at 1615 to radiate 77.01 watts at 1.8V, ambient is 21°, cpu temp is 32° that gave me an c/w of approx 14 (fans at full speed that is). so i don't think these kits are for anything more than scared people (i understand, we're talking bout a lot of money down the drain if u screw up)
<rant>
what would make my respect for tomshardware return is a watercooling roundup of DD, swiftech, cuplex,... blocks on different tubing. a nice radiator and pump roundup would also be appreciated. i can figure that that would mean loads of work for em review boys, but i guess it would interest ppl alot more than c 20 , 20 page review of motherboards or ti4200 that all score in a 1% range of eachother (with tolerance errors that means jack shit)

So... with my Via 1300, the issue has nothing to do with gluing the shaft to the impellor (can you do that?) It's basically just a more noise making pump? Damn wtf, what a rip! But I guess for 370GPH@$23 you can't get any better... and I'm not about to drop tons of money into an overpriced/rated Eheim/Danner... No offense, they make some of the best pumps, but the price is just ridiculous, including the size they make-- needed to equal this loud Via 1300/Rio series pumps. Guess I'm just stuck with loudness...stupid Via!!!

bigben2k · 07-18-2002, 04:36 PM

(my posts seem to dissapear!)
Mkosem has the same pump, and he says it's whisper quiet.

I'm going to advance gmat's idea: maybe you have a bent shaft. You'd need to replace it.

V12|V12 · 07-18-2002, 04:54 PM

Well I'll be damned! Cheap Via using the flimsiest plastic tube/shaft they can... I was wondering that when I was looking over everything before I installed it... And about getting a new shaft, heh, what a hassle that is going to be!!!

bigben2k · 07-18-2002, 04:55 PM

Just for kicks... does it make the same noise if you're just pumping water in and out of a bucket with it?
(i.e. a no-load test)

V12|V12 · 07-18-2002, 05:02 PM

Hrmm, I'm not sure, I can't remember that far back, but I'll certainly try it out when I get around to changing the system... I think that the sensor just won't read below 40C... :shrug:
