To 24/7 or Not to 24/7. That is the question!
 

Alright guys, how many of you 24/7 you pumps? i know i do!
dam relays are like 30 bucks! plus my rig's always on anyways!
My rig

24/7 because my rig is on 24/7 and a relay is just a waste of time and money. :D

Got me TEC'ed rig, use to have it24/7 folding but was to expensive (two TECs) on electricity front and I stopped:(

For the time being, I unplug my pump and rad fans manually when I shut my machine down (which is not very often). Once I get my new tower and finally am able to build everything inside of it, I will have a somewhat extravagant setup that allows me to set the pump to either be on no matter what, off no matter what (using a momentary-type switch for safety) or be controlled by a relay on the PSU like most people do. The rad fans will also be powered independently of the main PSU and there will be a switch to set them to constantly on or PSU relay controlled. This way it will be easy to fill and bleed the system, as well as do quick checks by cycling the pump off and back on, etc.

I don't see any advantage to leaving the pump running constantly when the computer is powered down. Every pump has a lifespan, and each rotation just counts up on the odometer. I wouldn't mind setting up a circuit that would keep my pump and fans running for 20 or 30 seconds after a power down just to suck any remaining heat out of the machine instead of just letting it sit there and cook with no ventilation.

Occasionally, very ocasionaly when my computer is on the blink (about once a month) I switch everything of... normally it just runds 24/7 anyways. been swicted off about 8 times or so in a year.

Still works/.

I dont shut off the computer to do a fill and bleed. Its been off for about 15 minutes so far this year and that was only to replace the pump.

I fold 24/7 ;)

I've one particular pump that's a year and a half old; it's been running the whole time except for a 30 minute break to move the computer to another room.

How come the non-24/7 people aren't talkin?

I usually leave my PC on 24/7, but I'll slap it in sleep mode, overnight. When I add the water cooling component, I'll be turning it off when not in use.

If I had straight water cooled rig I'd have been running it 24/7 for sure....

24/7 for about the yr and a half now. Occasionally off for maintenance and when I'm out from home for vacation. No problems at all :D

Cheers!

Allways on. The only time it goes down is mainteniens or a sec to reboot after ANOTHER! M$ update :confused:

24/7, Linux boxes don't need periodic rebooting. My box only goes down for hardware updates, moving, or other such tasks.

Gooserider

24/7 as well... I used to run an FTP off it... now my water cooling rig is used as the backup for the FTP...

it's on for about 8 hours weekdays, and about 14 hours on weekend.

I shut it off when I got to school or sleep. Besides folding there's no reason to keep it on, and it makes my electric bill too high with the TEC and such.

Hey Groth, i think they aren't talking because they are ASHAMED!
:D muhaha!
:cool:

Not really.
I dont use seti, ud, or others ... never liked those things.
I dont "download the internet" like alot of people do. I usually just borrow their hard drive, less hassle (and get all the goodies too). :D

I dont keep it on just "because"...
Only on when actually doing something.
Still, it's on most of the days. But not 24/7.
Besides. No "waste" of electricity.

how can it help find a cure (FOLD!) if its not on?

I'm not going to apologize for finding "folding" irrelevant.
It simply strikes me as such. Wasting energy. Making alot of internet traffic thou.
I have yet to be proven that those programs actually do something, or have done. Maybe i'm wrong. But yet to be proven .
No source, except from those "dubious news sites" , have references of.

Anyway.
Some of my friends that do fold, most of the time use the numbers in a "dick size" way. Not for me, thanks.
Same as scores in 3dmark , Aquamark or others.
Dick size talk most of the times. No good out of it.

I've seen proof that at least one can do "something". I've got a buddy that ran one computer pretty much only as a router/seti@home folder for years. But they (his family) left the monitor on. The screensaver has actually burned into the monitor (and yes, it's a nice modern-ish one). Feels kinda funny saying a screensaver would do that, but it's true.

Now as far as doing something useful, aren't there some sub-ambient pelt cooling guys who need to keep cpu at ~full load so as to keep temps stable?

Hehe.
Didn't hear that before.
Burned into how? I mean, it just sounds odd. :)
Like a picture?

gruntledweasle & TerraMex,

I know phosphorus "burning" or "ghosting" in monitors can happen, but is usually avoided in modern monitors due to their power saving features.

i.e. - They turn off the display after a set amount of inactivity.

LCD monitors are NOT at risk to this at all.

Most modern systems are like a car... if you drive lots of highway miles (don't shut it off much and keep it moving) then it will last longer (statistically speaking).

Hard drives spinning up and spinning down are the major cause of failure. I work in the Telco industry... we have hard drives that have been spinning for almost 20 years... they only fail when we have a power failure that causes a system shutdown.

Terramex: More like an overlay...there's just a ghostly image overlaying the actual screen. I'd post a pic if the machine in question weren't half a continent away from me.

I thought this was common knowledge, but here's a link.

MMZ_TimeLord: Um, I already knew that stuff. Which is why I made a point of noting that the monitor was relatively modern, and that it was not set to turn off (that's an OS function, not monitor). Modern CRT monitors will burn in if you give 'em enough time.

I just thought it was funny that a screensaver app caused burn-in. I hope I didn't give off the impression that I thought this was some kind of serious risk associated with distributed computing?

gruntledweasel,

Not at all.. I just wanted to clarify... :D

funny thing is screen savers were originally for old black and white monitors
they aren't needed for todays color monitors as time to burn on modern monitors takes MONTHS of consistant image.
maybe that monitor was overpowering the tube and thats what cased the burn, or a weak weak phosperous layer.
dont you guys just love my spellen!

I know what a screensaver is. ;)
Just never heard of ghosting (as MMZ nicely put it). We still have a few 14" oldies (including a smaller 13" black and white monitor for the novell server). Never seen those events (and those were abused monitors).
I know the phosphorus layer does get "yellow" by usage (and age), and starts loosing brightness, but never actually heard of the cathode burning an image on the layer (doesnt it have to damage the colour grid too?...) .
Always thought that the cathode didnt have enough power for that.
Anyway, sounds a nice thing to have on display (pun intended). :D

We're not talking about months so much as years. They barely used that computer for anything, except routing stuff. The closest thing I've seen is "taskbar burn" on a crap office monitor that had been running win95/98 for ages.

There's another funny story about that computer. I remember a LAN party we had where half-life wouldn't run on most of our PCs. Executable had been modified by a virus, and so it refused to start (nice feature, that!). After the scan and disinfect orgy, we tried scanning the router. Thing had well over 40K infected files, from over a dozen different viruses. :eek: It was so virusified that we had to scan it over the network. In fact, I think 40K wasn't the actual number of infected files. We just got sick of tying up one guy's computer with scanning duty, and the owner of the router had long since given up hope for anything other than a reformat.

Another 24/7 here.

I have always run 24/7 since I believe that it is better for teh hardware (some past IBM hard drives notwitstanding;))
Since I keep 'em running anyway, I do participate in DC project (s).
Systems: 4
Eheim 1048 that has been running almost constantly for a few years.
3 Eheim 1250s of various ages from about 2 years to 1 year.

Computers are turned off for modding and part swaps only.
Reboots are as infrequent as possible- since I use Linux and Win2k, uptimes of months are the rule. :)

I run my computer about 4-5 hours a day, turn it off when I sleep, then go to work/school then get home and turn it on

24/7 here and will be 24/7 when I get all the W/C stuff hooked up also. Of course I'll have to shut it off when I switch over to W/C, hopefully by the end of the week. All the stuf is here just waiting on the top of my PC-76. It at a buddys shop getting 3 yes three 120 holes cut in it to fit a ThermoChill HE120 3 rad.
