Carlito4977 Posted September 3, 2007 Share Posted September 3, 2007 as with any other electronic appliance, its life is shortened by stress brought about by several energy sources such as heat, electricity, etc.I agree. It depends on how much you really need to open your PC. If you can make it rest, of course it is for the better. But if you think you could gain more by leaving it open, by all means do it. Frequent on and off could also shorten the lifespan of your PC. Power outages, cold solders, and leaked capacitors, are just some of the probable effects of frequent on and off. Quote Link to comment
mistere57 Posted September 30, 2007 Share Posted September 30, 2007 i dont think theres anything really wrong with leaving your pc open 24/7 ang nakakatakot lang talaga is yung mga spikes and fluctuations ng kuryente tapos pag overheat ng psu... cgro just make sure well ventilated at protected lang para di naman madali masira yung pc mo... i remember my old athlon xp na bumigay lang yung capacitors ng board after 5 years... it was on 24/7 majority of the time kc nk dial up pa ko before kya sinusulit ko yung mga madaling araw for downloads tapos i use it for my work and personals during the day...

gatlobil Posted October 7, 2007 Share Posted October 7, 2007 is it ok for home desktops or pc's to be open at an average of lets say 6 days a week? ung tipong walang pahinga. iniiwan lang bukas kapag kakain, tapos iiwan din bukas kpg matutulog na dahil may tinatapos na madownload. basta palaging bukas ung pc. ok lng b or madaling masira? ano naman ang unang massira? need your opinions here...tnx... there have been a lot of discussion in other forums regarding this for as long as I can remember. The biggest issue today in heat, therefore a good cooling system is required if you're planning to keep your computer running 24/7. Another issue is power surge/fluctuation. This is the second biggest killer in your system. A lot of people will actually recommend running your system 24/7, rather than turning it on for a few minutes or hour the turning it off, then on again, off again, then on.. you know what I mean.. Having your PC turned on constantly minimizes the power surge going through your system everytime you power-up. More power is needed to turn-on a PC than it is needed to run it..that is why, when having problems with your pc, avoid pulling the plug from the outlen or the back of your PC or pressing the power button. Try resetting the pc first kasi di masyado nagbabago ang amount the kuryente sa PC components mo. When keeping your PC on 24/7 just make sure you have decent power surge protetor, wag yung mga murang AVR na nabibili for around 500 pesos or less, better yet, make sure you have decent UPS before you consider leaving your system on 24/7.. Of course don't forget na kelangan pa rin ng system mo ng maintenance so there should also be a downtime para mag-cool down yung PC mo (para bang bakasyon after a long time sa trabahao) Quote Link to comment
EvilAgent Posted November 7, 2007 Share Posted November 7, 2007 since i learn how to operate a desktop computer and link it to internet i never turn my computer off except for situations of maintenance and special something... i never had a problem with it naman my very first computer pentium 1 runs for 1 yr and let it rest due to update (i had an amd duron)... they said amd processors heat up easily i dont think so.. i dont have aircon in my room but im keeping it alive (downloading porns) imagine downloading 100mb then using a 56k dial up connection... you need patience hehehhe .... for my laptop try to reserve your lcd monitor.. lcd monitor have a life limit... so its not advisable to turn your laptop 24/7 Quote Link to comment
ilb4u2nyt Posted November 8, 2007 Share Posted November 8, 2007 a UPS and a good quality ventilation for the pc is one good factor for keeping it alive and kicking 24/7. Seen an online account server for data transaction working for more than 2 years none stop because of hot-swapping capability and redundancy of system backups and components. Quote Link to comment
boomouse Posted November 10, 2007 Share Posted November 10, 2007 as with any other electronic appliance, its life is shortened by stress brought about by several energy sources such as heat, electricity, etc. No. what will shorten the life of your computer is what engineers call 'thermal cycling' -- the cycle of cooling down and heating up computer components when they are regularly turned on and then off. Remember you have thin metal of various materials and various linear expansion coefficients attached to a thermall stable substrate like mica. Over time, the stress of expansion and contraction will cause solder points to produce gaps which will lead to untraceable hardware errors because of the minute electrical values involved. When you think that a solder on a circuit board gave out because of heat it is actually more because of this process of cooling down and heating up. Under these conditions, mediocre quality solder points will give out over time. This is why it is best to keep the temp of your circuits stable by keeping them on with adequate airconditioning/ventilation. My rule of thumb is that for as long as inside box temperatures are 10 degrees C higher than ambient then it is okay. Laptops are a different story. They use low power components and give off and produce less heat so thermal cycling is less of an issue. Quote Link to comment
idunno Posted December 7, 2007 Share Posted December 7, 2007 If you are turning on your PC for 24/7 downloading (torrent, etc.) then just use a laptop rather than a full blown desktop PC. - You don't need high computational power in download (it's not like your crunching numbers to solve a biochemical problem)- Laptops consumes less power (don't contribute to the global warming)- Lesser noise so you can sleep peacefully- You have a built-in UPS system in your laptop because of the battery system (less danger with power surges) Quote Link to comment

A lot of people will actually recommend running your system 24/7, rather than turning it on for a few minutes or hour the turning it off, then on again, off again, then on.. you know what I mean.. This is actually an old wives tale. The reason you want your computer on all the time is so that you want to eliminate the biggest source of stress on electronic components and it is not the heat. A properly designed computer will always be able to handle heat buildup. A decent PSU will be able to handle fluctuating electricity within a certain range, say 190vac to 240 vac. This is because it uses a 'switching' ower transistor to mitigate the voltage fluctuations. What you want is a powerline filter that will trap any sudden spikes in electricity and or suppress surges. The main source of long-term unreliability in any electronic device is what you call thermal cycling. This happens when the tempretature of a device is caused to regularly go up and down due to a cycle of turning it on and turning it off. For example, in a high humidity country like the Philippines turning off your office computer at the end of the day will allow the components to cool down to the point where the colder pre-cooled office air can allow the appearance of condensation on the electronic circuits. Remember you no longer have the system heat AND the cooling fans to prevent this. So, if some condensate just happens to be in the right place between say two sensitive connections when you turn on your computer in the morning you will soon start having problems and it will drive you crazy trying to figure out why.

kimkulit Posted December 28, 2007 Share Posted December 28, 2007 so sir dapat may fan/aircon 24/7? to maintain the temp kahit off ang pc? for example off ko computer ko pero un fan itutuk ko sa pc? ganun ba? Quote Link to comment

If you can have a fan cycling air through your PC box even when it is off that will help a lot because you will prevent condensate from forming on the circuits. Quote Link to comment
hondacity Posted February 11, 2008 Share Posted February 11, 2008 my pc runs 24/7 no restarts yet... Quote Link to comment
m777 Posted March 12, 2008 Share Posted March 12, 2008 my desktop pc also runs 24/7. no problems :thumbsupsmiley: Quote Link to comment
ReDHeaD Posted March 13, 2008 Share Posted March 13, 2008 mine's running or has been on for about 6 months now. pero sympre minsan tinatapatan ko ng fan lalo na pag mainit panahon. it's good to restart it once in a while as well pag bumabagal na Quote Link to comment
neybor Posted March 23, 2008 Share Posted March 23, 2008 (edited) hindi lang dapat good ventilation ang gagawin if your running your pc 24/7 shempre once in a while you need to check if meron ng nakakapasok na mga malware etc sa system mo..before doing that 24/7 operation..need first to secure you pc.. Edited March 23, 2008 by neybor Quote Link to comment
hondacity Posted March 23, 2008 Share Posted March 23, 2008 why check? i have my av set to scan at 3am...and my anti-spyware at 5am...at 7am...so far walang problems... thats automation to simply put it... Quote Link to comment
