Reasons why capacitors swell!

Hello!!! Although temperature is one of the factors in the swelling of capacitors, the reason is not directly linked to ventilation; the temperature rises due to: an electrical spike, poor regulation of the power supply voltages, or simply a short circuit in the capacitor itself. Ventilation is a factor when, because it is inefficient, the processor or chip discharges a spike into that capacitor. Higher temperature = higher power consumption.<br />Los enlaces son solo para miembros.

<br /><br />Thank you very much for your additional information, which is extremely USEFUL! Keep that in mind too..<br /><br />Cheers and thanks!

Excellent information guys... I've fixed this problem a couple of times and didn't know exactly why it happened xD<br />Thanks...<br /><br /><br />REGARDS

This time I bring a video tutorial on how to measure a capacitor. You may say I didn't make it, but the reason it's here is to save you the trouble of browsing and watching dozens of videos and then filtering and picking the best one; well, I did that ;)  . I hope it's useful for cases where a capacitor doesn't look swollen but you're suspicious of it.<br /><br />Los enlaces son solo para miembros. Registrate o iniciá sesión<br /><br />REGARDS !!!

<br /><br />Thank you very much for your little help C4TT4NN4, it's useful. Here I bring you another little video, better explained and very useful, on how to replace capacitors.. It's not hard at all but you need the necessary tools to do it!<br /><br />Los enlaces son solo para miembros. Registrate o iniciá sesión<br /><br />Bye and I hope it was useful!<br /><br />Regards

ZyXEL I owe you an apology for how short the "little video" was, but it was only meant for learning to detect faults in a capacitor that doesn't work and is "NOT" "swollen". Your contribution on the subsequent replacement of them once the mentioned anomaly is detected is also appreciated. The video I posted about fault detection is for when we have this: <br /><br />Los enlaces son solo para miembros. Registrate o iniciá sesión<br /><br />And when checking our hardware, that is, connections (cables, plugs, Socket, etc.), HDD with programs like Everest, memory (cleaning contacts), power supply (checking voltages), or a visual inspection of the Motherboard looking for faults visible to the naked eye (inflated or swollen capacitors).<br /><br />Los enlaces son solo para miembros.

<br /><br />No problem! Whenever I can contribute and I know or can help with a topic I know and understand clearly, I'll do it..BUT talking nonsense, no!<br /><br />A THOUSAND thanks for your added information, and with this we wrap up the post since it's now REALLY complete, and anyone who reads it and watches the videos will be able to fix it without any problem! Just be careful with the motherboard PINS, they're fragile!!!<br /><br />Cheers and a thousand thanks!

You should know that capacitors can only withstand heat up to a certain point, so you need good coolers with a good RPM speed so that neither the components nor the capacitors reach high temperatures.<br /><br />If you have this problem with your capacitors, the first and main thing you should do is add one more cooler, or as many as you want and are willing to pay for, and you should also clean the PC and its coolers every now and then, along with the fan cooler, which tends to accumulate a lot of dust, and that can cause problems such as the PC suddenly shutting down, etc..<br /><br />Well, this is my other humble contribution and I hope it was very useful to you!<br /><br />Cheers!<br />

<br />good afternoon, I need help clearing up a doubt about electrical capacitors. I have an acer aspire  m3610  and last friday we turned it off at night as always, then on friday when I went to turn it on  the screen didn't turn on, so I turned it off and on monday I called my insurance (mapfre), they came on wednesday, brought a new screen and when plugged in it does turn on, but when turning on the pc, the tower powers on but nothing reaches the screen, so he thinks it might be the power supply, sees it isn't  and then he plugs in my screen and a  laptop adapter and my screen works  :o :o that's when  he looks at the tower and tells me the motherboard is broken,  that there are two  swollen electrical capacitors that belong to the graphics card, but that my tower has it integrated<br />according to this technician those capacitors  don't show damage from power surges but from wear  and that the tft has a bad oscillator  <br />my question is the following: my pc hasn't given me any problems lately that would indicate something could be wrong  <br />that those capacitors broke overnight;  I'm in an area where voltage highs and lows are an everyday thing, that's why I doubt it was from wear,, if that's what his report says  the repair isn't covered by the insurance  <br />thanks in advance and I eagerly await your answer . later I'll take a photo of the capacitors<br /><br />

<br /><br />please write properly, and also create a new topic, don't revive topics from last year. That aside, I highly doubt it's from wear; given the conditions you mention, it's most likely due to power consumption. Nevertheless, my recommendation: take the computer to another technician and have them tell you what it is, give you a quote and explain that it's due to x reason, then go to the insurance company and file a claim saying the other technician was wrong.<br /><br />regards!

Wouldn't it be better to replace the capacitors with ones with a higher voltage rating because there's overload? dude
