so one of my followers on Twitter asked for an update on the wife PC as you guys may or may not recall I rearranged the airflow configuration because I was trying to avoid the default config which is these fans blowing out and these fans sucking air in I was of trying to avoid the default configs tendency to accumulate dust rings on the front fan grill so what I've first had planned to do was create a positive air pressure environment but that didn't really help because anywhere where air was being drawn in I was still getting that that dust accumulation so what I've gone with now is a single intake at the back so that is running off of the CPU fan header with a voltage reducer in line so that it's running nice and quiet and nice and slow actually the sound you hear right now isn't the fan but actually it's the coil whine from the GPU because I have fur mark as well as prime95 running right now so that you guys can see what the temperatures are like the fact that it's off the ground also helps a fair bit in terms of accumulating dust inside so it's uh yeah far less far less likely far less liable to do that so let's go ahead and open it up I'll show you guys what the guts are looking like these days so I did end up changing the motherboard oops there goes the Wi-Fi antenna oh well whatever so I didn't end up changing the motherboard right now I've got an MSI z68 AG dat in there nice high-end board I robust cooling on the voltage regulator modules is good because I don't have a whole lot of cooling otherwise in this system so the two top fans are disabled bear off and there are no fans in the front so that is how I'm keeping those dust rings out and I'm maintaining the positive air pressure just by having just one intake fan and it might be positive it might actually be more neutral because this is also an exhaust so this is pulling heat away from the GPU which is running quite toasty but nots to be expected it is running fur mark which also has a single 120 millimeter fan running on the aftermarket cooler that is on there so that is pretty much it there's nothing really in the front of the case that needs to be cooled all we've got is one SSD in here there are no hard drives this system relies 100% on network storage for its mass storage you can see the configuration of that video card so there's a bunch of hietzing somewhat not all over if that's a 5870 it does still have a what is in there it's a 2600 K as well as 8 gigs of - Edition ocz memory and azam tech X mystique that's an older PCI sound card as well as a gigabyte Wi-Fi bluetooth card in there as well so the config hasn't changed much I just redid the motherboard I unplugged all the fans I switched the power supply around so that this would act as an exhaust for the hot air coming off of the graphics card because that's really really toasty and I didn't want to blow it the other way up towards the CPU cooler because especially in a in a heavy load environment running the CPU passive like that is is pretty pretty tough it's really asking for a lot now bear in mind guys the system is not overclocked in any way sorry I'm just adjusting something there I want to close this up here before I show you guys any more hold on I'm just going to let the camera hang for a bit I apologize if this is like motion sickness inducing because there's just nothing else I can really do with it right now okay their case is closed up because I want to show you guys on closed side panel temperatures when I show you the prime95 fur mark temps better going on in here so again the system is not very loud not coil whine you hear is from the graphics card will turn off when when we turn off firm art for mark really does a number on graphics cards and I found especially the last few generations AMD cards ah well if they wanted a little bit alright here we go so CPU temps with 8 threads of prime95 are around 60 degrees which are super acceptable and fur Marc's been running for the last little bit here and it looks like we're going to peak around that sort of 76 to 77 down to 76 a look at that good timing we just hit the peak right around right around the time that we stopped that we stopped filming here and I stopped talking about it so you can see now it's really balanced itself out a fair bit so I think that pretty much covers it so the 5870 is more than happy running at around 75 80 degrees under load and if we go ahead and turn all this stuff off so if we stop our torture test put that away turn off firm art you're going to see that idle temperatures are very very good as well so like I said wouldn't recommend overclocking like this but if you have a case that is well ventilated in terms of just allowing passive airflow to go through it you know heat does tend to rise a little bit you can get away with very few fans so there's only a few fans okay here much quieter now that was that quell line from the graphics card before so very few fans 120mm are sorry 140 ml here 120 ml in the power supply and then that 120 ml directly on the video card and that's about it I mean if you didn't have a video card and you have like a passive power supply like like this x-series one from C sonic here you could get away with just a single single cooling fan blowing air towards the heatsink and that's about it remember guys that CPU is technically not a hundred percent passive because I do have that nearby fan blowing air at it so I think that pretty much covers I think is going to be a while before this settles down into and into an idle reading here but whatever you guys get the point thank you for checking up this update on my video blog and don't forget to subscribe to Linus tech tips oh yeah for those of you who are definitely going to ask that's the fractal design arc midi case love it
