[quote=Vynertje]That's pretty standard. The difference between absolute idle (for me about 37 degrees) and launching chrome (CPU usage jumping up to 70% in a fraction of a second causing it to spike [i](EDIT: forgot a word which made it look really awkward) to[/i] 50 degrees) is always rather big.[/quote]

[quote=HiFromBuddha]Well, everything for the most part is going swimmingly. Thanks, all.[/quote]

[quote=Vaan99]Holy shit >90°C on i5 2500 is insane. I'm glad you managed to solve it, I'd recommend you to take cooler completely off, clean it and replace thermal paste. You mentioned that one fan was full of dust, that means you haven't probably opened and cleaned your pc for quite some time, it might be very beneficial to do it. Just use compressed air to blow everything out and vacuum cleaner (but very carefully). To be honest with that pc specs you should be running lol at much higher than 60 fps and with 0 lag or stuttering. Your pc is still pretty good, even though i5 2500 is few years old it's still very relevant and shouldn't bottleneck in any game at 1080p. If you are considering upgrade, start with gpu.[/quote]

[quote=mastrer1000]Alright, let's talk airflow. Here is the current inside of my case(Shitty even for a cell phone pic, but you can see where the fans are): [img=http://i.imgur.com/hc5pvj7.jpg width=900] I just bought 2 more fans(I also still have the ones that came with my case, but they are pretty loud) and this is where I wanna install them. I also added the direction in which the air flows through each fan to the pic. [img=http://i.imgur.com/haumPBP.jpg width=900] One fan will go where my drive cage currently is(I'd obviously have to move my hard drive to the cd drive), because my gpu gets really hot and some airflow should help with that. The other fan can either go where it is marked on the picture below or to the spot directly above the cpu cooler(nextr to the marked spot). Other(less viable unless I am completly wrong) options would be to put it in the bottom of my case which would prohably make 0 sense or in my side panel which would be pretty annoying whenever I open my pc. Would the spot directly above the cpu cooler or the spot marked on my pic be better? My cpu runs pretty cool(around 55°C max), so it shouldn't really need more air. On the other hand, I am not sure how much putting the fan in the other spot would accomplish. [size=1] Yes, I will redo my cable management while I'm at it[/size][/quote]

[quote=Vynertje]I'd place that one just above your CPU cooler so the air flows nicely through the heatsink instead of cutting off just before that. If anything though, I'd probably mount the fan in the bottom part as intake for the GPU (you can add some raster kind of thing to make sure the cables don't get in the way), though that might give you an overkill on intake fans. Also yeah that's the most hideous cable management I've seen in quite some time :p This is how I have set up my cooling right now. I'm contemplating removing the top-right 140mm fan but in general it's cooling rather effectively like this. It's also quite quiet :) [img=http://i.gyazo.com/4a84be0d8a153fd16e254fc8f05c7ff7.jpg][/quote]

[quote=mastrer1000]Now I remember why I didn't do more than to get the cables out of the way of the direct path between my intake and my outtake fan back when I first build my pc. Also qq I don't have splitters for my fan cables, so I had to have one fan directly powered by the psu. The noise is bearable with a low noise adapter though, so I can use it until I get a splitter cable.[/quote]

That brings more air through the CPU heatsink. BUT you should obviously not be pushing air down with that fan. You should have roughly equal volumes of air being pushed out to the volumes pushed in for a optimal airflow. You have four fans of similar CMM (Cubic Meters/Minute, CFM is the commonly used term, but fuck stupid measurements like Feet), so you should use two for intake and two for exhaust. And since hot air travels upwards and you have two intake fans in the front you should obviously push air out near the back/top of your case. And if your fans push differing amounts of air (you can usually approximate through the RPM) you can just use undervolting to lower the speed of some of them (i.e: those adapters you put between the cable and motherboard). Also, isn't your PSU mounted upside-down? Are there not ventilation holes beneath the PSU? The fan should be sucking air from the bottom. That not only improves the airflow inside the case, but also helps keep the PSU itself cooler, which also might further reduce the temperature in the case. [quote][size=1]Yes, I will redo my cable management while I'm at it[/size][/quote] Yeah... You probably should. I mean, my case is significantly tidier than yours and I don't even have a modular PSU. Just chuck all the cords behind the motherboard plate. Works wonders for me :) I doubt you'll find many setups that are more open than mine. I even have VLP (Very Low Profile) RAM. [spoiler=My setup][img width=900]http://i.imgur.com/FlwPMIr.jpg[/img][/spoiler] Been using the shitty Intel cooler since I upgraded since my old cooler didn't fit. But the airflow in my case is so good that I have no problems keeping the CPU cool even with the Intel cooler. I have two 140mm fans in the front, both running at 5V. I only have a single 140mm exhaust fan in the back, but because of this I put [url=http://www.corsair.com/en/air-series-af140-quiet-edition-high-airflow-140mm-fan]my most powerful fan[/url] there and only undervolt it to 7V (full speed is at 12V). All in all, roughly the same amount of air pushed in as is pushed out. The setup is whisper quiet with very good temps aside from the CPU, for obvious reasons.[/quote]

[quote=Vynertje]Having more exhaust than intake isn't necessarily bad either. It is a really effective way of dissipating heat but the downside is that air can be sucked in through non-filtered intakes instead of through the front/bottom filters (I have 3 100+ CFM fans set as exhaust, oops). That's why most people recommend slightly positive airflow (slightly more intake than exhaust). Also you're quite right on the part of PSU mounting - unless you've got your PC on very dense carpet (which can block the intake). Can't really see much on those photo's ;) Personally I've set my case fans to 4V and 7V for my CPU fan. I use a PWM fan hub to speed up the fans if necessary but that only happens once my CPU goes past 60°C (heavy gaming load). In idle it's pretty much inaudible and only if I play Witcher 3 (or any VERY intensive game alike) for more than 15-30 minutes the fan noise will become audible (mostly my GPU).[/quote]

[quote=Searz][quote=Vynertje](I have 3 100+ CFM fans set as exhaust, oops)[/quote] 3*100+? That's a looot of air. Even when undervolted to 4V they likely move more than 100CFM. That's far from what I'd call "inaudible". My setup moves about 50CFM and I can still hear it. It's very, very quiet of course, but it's still not inaudible. Don't exaggerate. This isn't a pissing contest.[/quote]

This isn't a pissing contest.[/quote] I don't exaggerate, I use the product specs provided by the manufacturer ;) For the record, these are 1200 RPM fans. Also keep in mind that the Enthoo Luxe I'm using is doing a really good job directing the sound away from me and that I'm sitting at about 1m away from the chassis. [img]http://i.imgur.com/Ls8L7aG.png[/img] You may or may not believe me, but in a completely unrestricted situation -which is how I use them, I have more pressure optimized fans in intake - I actually do believe they move that much air. My old Corsair fans (AF120's) definitely didn't move as much air as these on the same RPM.[/quote]
