Done with EVGA power supplies

For the record. It is good to have the psu fan spinning even at the lowest rpm. Not having a fan run for a long time can/will cause long term damage.

I hate zero fan mode hardware.

I like it on GPUs personally, don't have much of an opinion on PSUs I haven't done the research nor do I have the background to comment on that.

But regarding gpus, I always rip them apart and use liquid metal and higher grade thermal pads.  Pretty cool to see the GPU fans not kick on till almost 1 minute of uniengine lol.  But that's with good airflow in the case.

I'd just get an AiO for the GPU with a high end silent fan on the radiator

 

I personally like stuff cooler even if there isn't a real difference while under 55ish degrees Celsius.

 

About your PSU issue I'm sorry you had bad experience with EVGA units, it could not be their fault though and your power source is the one to blame, who knows... what PSU are you running now and for how long?

PSU is actually still working fine, none of it's really EVGAs fault, I updated in my last post on second page if you wanna read through it.  On my girlfriends rig and my personal I have EVGA p2s right now, even in my old computer I'm using currently until I get a new motherboard and cpu is EVGA p2 and still going strong.  On that note, the old rig I'm currently using has an 8350, and wow is it performing WAYYY better than expected with a GTX 1080, I've been playing Fortnite, Paragon, and Dota 2 all at 1440p 60+fps max settings.  I know none of those are particularly demanding on the CPU side, but coming from 6800k back to 8350 I figured I'd get lots of stuttering.

 

I definitely like things running as cold as possible, but I'm not a fan of liquid, so far I can tame any Intel chip under 60c with air cooler under prime 95 while being more quiet than any radiator setup I have ever com across (after delidding), even 6700k I had at 5ghz still running cool, so I don't see the point in spending the extra money and dealing with liquid.

 

Increasing thermal transfer even makes your stuff use less power at the same voltage/frequency, little known truth.  After delidding with exact same settings usually notice 10-20 less watts from the wall.  Gamersnexus recently noted similar findings now that he is starting to delid.  I've had fx83xx chips that weren't stable at 4.8ghz, and replacing stock TiM with liquid metal is enough to not only make them stable at 4.8, but able to be pushed past 5.2ghz even when temps weren't an issue before delid.  Yes, I realize that AMD chips are soldered for the most part, but removing TiM (which in this case is the bottleneck) and switching to 15x higher thermal conductivity makes a HUGE difference on soldered chips, to the same effect as delidding Intel.  

 

Looks like I'll have an 8700k next week, anyone have experience with MSI Krait socket 1151 Mobos?  I don't really want to go with ASUS again lol, even though I really like their boards...

Well it is probably bad luck on your end. I have 2 EVGA 750W 80+ Gold ( 750 GQ model). I've had both of these PCs since November of last year. Mind you I live in California where we've had temperatures up to 110 Fahrenheit!!! Yet my PCs seem to do fine. Yes I do a bit of maintenance every few months to remove dust, but so far I've had zero issues. No winding noise, nothing!

 

This is coming from a guy who used to use Thermaltake (relatively inexpensive) PSUs and those always failed within a year or more.

No.  That's incorrect.  Sorry.  You're wrong.

Jonny beat me to it,A lot of psu now a days the fan only spins when it is needed.

Well, he is kinda right because a fan spinning at low RPM (something like 300rpm or so) cools it better than no airflow at all thus reducing the temperature of components dramatically.

And also lesser start/stop cycles for the fan...

You are correcting jonnyGURU... I promise he knows what he’s talking about

 

And the fan running without a need is just going to make you have to replace the fan earlier than necessary, with no gain in longevity for the OSU

Well, no.  Stefan is mostly right.  With the fan doing constant start/stops, it does put wear and tear on the fan.  That said:  It should still last the warranty term.

 

Also, a fan spinning slower instead of full stop means that the fan doesn't have to spin as fast when components get too hot since there's already air flow.  When there's no air flow, the fan has to spin faster/longer to create enough positive pressure to exhaust excess heat and bring temps back down to a point where the fan can stop again.

 

I was talking more about the internal components.  When the PSU is "fanless" those components inside are nowhere near their derating curve, never mind their maximum operating temperature.  Their lives are not shortened.  The whole premise to "fanless PSUs" like the Nightjar and Seasonic's fanless is that they use more robust components typically used for higher wattage units and then remove the fan and label the PSU as a lower wattage.

 

If you think about it this way...  Whatever AC is not converted to DC becomes heat.  Given that PSUs are typically 90%+ efficient these days, you can easily extrapolate that that's not a lot of heat.
