Posted August 9, 2017 So I got a 7700k and a 1080ti a bit back and have had some ridiculous temps (cpu 95c gpu 82c). so after checking everything from the cpus bios settings and re apply the cooler I pulled the front panel off my case and gpu never passed 80c and cpu never passed 75c! Naturally I started moving fans around to see what I could do to keep the front panel on and achieve better temps. first thing that made a huge difference was moving the top exhuast fan and making it a intake and then I added another fan to the front of the case. temps were a bit better (85c cpu 80 gpu) but still pretty hot. specs are cpu 7700k gpu 1080ti case phanteks p400s(tempered glass) cpu cooler be quiet dark rock 3 case fans 2 roswell hyperborea 140mm front 1 stock 120mm fan in back 1 in front and 1 thermaltake 120 mm on the top From what I have been thinking the temp difference must be from the hot air of the gpu( non reference) going up to the cpu. do you guys think a tiny 80mm fan as exhuast on the pci vents would help, or maybe even a pci slot cooler?

Two case fans in the front and one in the rear is the best configuration for temps. Anything more than that offers significantly diminishing returns...

Posted August 9, 2017 Yeah, the P400 (or really any Phanteks case it seems) has garbage airflow. I wanted to go for that case, but the terrible intake made me reconsider. There is not much you can do unfortunately, except taking the front off. It's mostly about the sub optimal intake (because of the huge flat front), so installing more outake fans won't do a much good.. It's still about not enough fresh air reaching the components. Maybe the 80mm fan can help with getting rid of some hot air.. But without cold air 'replacing' it, you wont be doing much.

Posted August 9, 2017 These cases with tempered glass panels are really show pieces and imo, should only be used for closed loops. The glass acts a trap for heat and just holds it in the case. If you don't wanna use a closed loop, I would seriously go with a traditional mesh based case. I had to add a front intake to my INWIN for this very reason, and I used a 240, 360 and 120mm rads in my loop my 1080 on water was hitting 65C which is way too high, adding that fan dropped it 10C Ryzen Ram Guide My Project Logs Iced Blood Temporal Snow Temporal Snow Ryzen Refresh CPU - Ryzen 1700 @ 4Ghz Motherboard - Gigabyte AX370 Aorus Gaming 5 Ram - 16Gb GSkill Trident Z RGB 3200 GPU - Palit 1080GTX Gamerock Premium Storage - Samsung XP941 256GB, Crucial MX300 525GB, Seagate Barracuda 1TB PSU - Fractal Design Newton R3 1000W Case - INWIN 303 White Display - Asus PG278Q Gsync 144hz 1440P Link to comment Share on other sites More sharing options...

I noticed only with front off did I truly achieve positive pressure, when the front was on even with the extra fan on and all at 100% there was still some slight negative flow but maybe it is more negative than it seems, would it be silly to add another top intake over the cooler? would higher pressure fans help with the front panel, the hyperborea are rated at 2.2 tho...

Posted August 9, 2017 Author yeah i did it with the side panel off and thats a whole different thing. I have never noticed the heat but maybe its too thick so next time ill feel the inside. I kind of doubt it tho but I might try using a different panel and see if it helps. Link to comment Share on other sites More sharing options...

But I said with the front on adding just 1 intake changed temps dramatically In fact I did read what you wrote, hence my reply. An 80mm PCI-E fan, if that exists I'm not sure, would not help. It might make your gpu a little cooler if you were to use it as an intake, but would introduce more dust. And as an exhaust it would do nothing, since the GPU would push air up and away from that fan.

I would agree with that statement in a normal situation but Im saying in the context of the situation there is a problem with the airflow due to the phanteks poor front panel design. I need some way to force more air through the front. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

I need some way to force more air through the front. If you're using stock fans, you could try some static pressure fans to try to pull more air through. You could leave the front panel off if it doesn't bother you. Or like Stealth80 did, modify it to be a mesh front. People have done this to other phanteks cases like the Evolv ATX.

As long as the case has good airflow it doesn't matter if your side panel is a solid piece of glass or a solid piece of metal! The amount of heat held by either really shouldn't change your temps in a drastic way whatsoever. Air flow through the case is the culprit here , not the damn glass smh lol. It's just that the p400 front panel terribly restricts it i switched from a Phanteks Luxe case to the p400 and instantly seen a huge difference in temps. Also if I'm really taxing my GPU after awhile my fans will kick in at either 100% or close to it, but with the front panel off it doesn't get hot enough to do that. I'm going to either cut out a hole in the front for the two fans and put fan filters attached behind the panel with a grill on the front or i'm going to make a custom front panel out of acrylic.

I'm speaking from experience, you can literally feel the heat on the glass - ofc poor airtflow doesn't help, hence point about them being more for show pieces. All the top performing cases that I have seen don't have tempered glass panels. Also, this thread is 6 months old? My mod GPU temps dropped around 8C just adding that fan, the glass still gets hot after a good gaming session.
