Hey Doyll! Thank you for the detailed reply, I just want to be sure I'm understanding you and getting the most out of the case. I've not blocked the gaps around the fans just yet, as I built it quite recently and haven't got round to that part yet. Should I use electrical tape or similar to...

I think this is the way to go, as a while back I managed to boot to Windows @ 4.8Ghz and I think maybe even 4.9 (at least 4.85Ghz for sure), although that was just booting to Windows, the temps were way too high to do anything. Besides, if I fluff it up, I suppose I'll just have to get a nice...

I've actually made the switch now, and have the setup in the new Phanteks p400a case, with the Noctua Chromax, which fit just fine. I mounted the second fan on the back, rather than the front, due to clearance, and other than that, no clearance issues at all. The PC is now whisper-quiet in...

It's not, no - I've been meaning to, but keep putting it off as worried about breaking it.

See I've read about airflow being less effective than believed, but there's also a bugger load of evidence to suggest that exhaust (concurrent with airflow direction) would still assist. For example even GN standardised fan layout includes exhaust fan. And although up top isn't concurrent...

This is brilliant thank you doyll! I was watching some videos last night on Big air coolers which actually showed the same minor difference between the D15 and D15S, so I think I'll skip buying any 120s. I won't be able to use the second 140 that comes with the D15 cooler either way, and was...

I was actually wondering if removing the back pcie covers would be a good idea, would I not be paying a trade off with dust accumulation when the system is off though? I was also going to get a replacement 120mm fan to go on front of the dh15 (due to clearance), and use the 140mm that would...

Thanks for all the replies, I've gone for a p400a with a Noctua D15 Chromax, planning to take the front fan off if needed. Should be plenty overkill for a 4790k, so gives me room to play around with fans and whatnot. Thank you all, Martin

Corsair 4000D Airflow is one of the cases on my original post, but part picker said that the front panel on the case wouldn't work with my old z97 board, the newer 3.2 header not being compatible evidently.

That's the GN article I was thinking of, really goes to show why to avoid a setup like I currently have. Some of the cases I've listed have space for a 240 up top, only one had space for a 280, the Lian Li 215, but that had some other compatibility issues.

There's a GN video which showcases issues with tubes up top, the TL;DW is that in the short term you likely won't notice, but after a few years, with permeation and other effects, the pump is moving an ever greater amount of air through the block, which reduces performance, creates noise, and...

I didn't have this as an option as this would require having the tubes up top, which unfortunately reduces effectiveness, lifespan, and creates whine like in my current setup. P400a has been getting a lot of positive attention though, so I think it's got to be that case really. Thanks, M

The p400a comes with 3 rgb fans that GN said are the same as the none rgb versions, with it coming with 3 120s would you recommend still switching out to 2x140s? If so, I've got a couple corsair ml140s I could use up front, how would they compare against the ones you linked? I'll have a read...

Thank you for the replies, it seems to me that Big Air in the Phanteks p400a will be one of the better options to go for then. I think it's safe to say that any of these solutions would be better than my current setup in the Core 2300 case, as I'm likely seeing higher temperatures on the Vega...

That's the part I'm concerned about - If I squeeze Big Air into Phanteks p400a as an example, would there be sufficient airflow to allow the Vega to keep cool? Would my CPU temps be higher for having the Vega card right up against it as seen in the pic? It's been a long time since I've used...

Hi, Thanks for the reply - I am leaning more towards Big Air, but how would it affect GPU thermals for squeezing in such a massive block in a smaller case? Vega is already quite a hot chip, would I be trading GPU thermals for Big Air? (ie 10C hotter GPU for using Big Air due to airflow etc)...

Hi All, I'm looking to upgrade my existing case & CPU cooler in order to maximise the overclocking potential of my i7 4790k -------- Background: I have an older pc setup (4790k) in a Fractal Design Core 2300 case. I'm using an Arctic Liquid Freezer 240 (the 1st, not 2nd) upfront, but the tubes...

I think you're absolutely right here, all the other smaller elements being overclocked seems to have affected something that tripped a failure in OCCT. Overvolting by a significant margin seemed to begin to stabilise this, until thermal limits ofc, but even then I was likely losing performance...

Hi Guys, After further investigation I've been able to stabilise the system, it seems that the BCLK at 105, even with all other clocks being conservative, was causing the OCCT test to fail. When reverting to BCLK of 100, with voltages and clocks being mostly the same, the test is now able to...

Or so I thought! I managed to improve the above by reducing my RAM and System agent voltages slightly, and had passed all stress tests, and played games for some time. I believed this to be stable until I downloaded the updated OCCT yesterday, 5.0.1, and long story short - my PC is unable to...
