Thanks. 

Id recommend either flipping or removing the exhaust fans in front of the cpu cooler as all they are achieving are sucking the fresh cool intake air straight out of the computer leaving the residual GPU air to cool the CPU, kinda like this

 

blue lines = cool air

red lines = warm air

Youll end up getting cooler temps and use less power (a tiny bit but still some) into the bargain

Recently bought a Noctua NH-12S Redux after the pump on my H100i began to die after nearly 10 years of on and off usage. 

 

The NH-12S is a great cooler and I noted in the instructions it can be oriented to face the back of the case or up to the top. 

 

I have 2x 120mm intake fans on the bottom, 2x 140mm intake at the front, 2x 120mm and 1x 140mm exhaust along the top and a single 140mm at the back. I should note that due to the case layout the fans don't blow towards the CPU cooler directly (please see photos). 

 

It's pointing to the back at the moment, would have turned it to blow to the top but the intake fan would be about an inch from the GPU (not that it probably makes much difference. 

 

I could also turn the top fans to intakes aswell but with only 1 exhaust I'm not so sure if that'd be a good idea. 

 

On a side note, the 4790K still runs hot and I'm considering having it sent off for a delid and TIM replacement with a milled copper IHS. I imagine that will have a greater affect on the cooling situation than which way the fan is pointing 😅

 

Thanks in advance

Front to back is the traditional way. That's what I'd do. As for the copper IHS, I would NOT do that. It would be a waste of $ in my opinion. You won't drop that much in terms of temp and that money would be better spent on other upgrades.

All your GPU heat is being sucked up past the CPU. Try sucking with the top fans to force the air out the back of the case. Maybe even remove all the slot blanking plates.

If you're interested in a product please download and read the manual first.

Don't forget to tag or quote in your reply if you want me to know you've answered or have another question.

Thanks, I'll keep it front to back. 

 

I don't have the budget at the moment to upgrade anything major and it works fine for playing modded Skyrim and Fallout 4 whenever I have the time to (which isn't very often these days 😪).

 

I may just get the delid and keep the stock IHS which is only £18 compared to the delid with the copper IHS replacement for £58.

Will give that a try later, never considered removing the blanking plates since they're below everything, will give it a go anyway.

delid for 18£ doesnt sound that bad despite how easy it is to delid a non soldered cpu considering youd still have to buy the liquid metal buy a generic shaving tool (to dissasemble and get a very thin razor) then align the ihs properly upon reseal

 

cooler wise why not a phantom spirit 120? similar price and competes with the nhd15 which makes the u12s redux look like a joke in comparison, once you delid that meek u12s redux is gonna be quite the limiter thats for sure and that noctua support is irrelevant if it cant even cool a ryzen 7 let alone a ryzen 9

 

board is a z97 extreme9 (identified by location of bios chips and postcode) which afaik should be pretty decent at mem frequency if the z97 ocf is anything to go by

 

ram wise even if its some trash samsung 4gbit is still gonna do atleast 2400 while slow is still better than the default 1600 jedec and if it happens to be hynix expect 2800 at the bare minimum and no lower as haswell imc should be better than even 32nm x58 imc and both my w3670 and w3680 can do atleast 2800 stable in triple channel and closer to 3000 in dual channel, a more realistic expectation would be around the 3200 mark for tuned dualrank 2x8 ddr3 on haswell

Spoiler

havent tested dualrank yet but if running 2800 dualchannel with some dualrank hynix 2gbit cfr sticks (hmt351u6cfr8c) on an i7 930 is anything to go by then that imc is unlikely to be phased at all by dualrank so youll only see board and maybe pcb limit at 3200+

I was going to get one of the Thermalright coolers but I couldn't find one that could be delivered soon enough (best I could find was waiting a week). 

 

Need to use my PC for some work related stuff and the NH-U12S Redux was available for next day delivery. 

 

Even with the h100i it always ran hot which is why I'm considering sending it away for the delid service. That and I don't think it had good numbers in the silicon lottery but oh well. It's an old system I can't really justify spending too much money on it for what it gets used for.

Are you themal throttling with the noctua? Are you going for max overclocking? If not, there is really no reason to delid it. You won't get much if any performance gain.

Not really, no. 

 

It's just something I've always wanted to do since I bought it 9 years ago 😅

 

Managed an all core 4.4Ghz OC and on stress tests cores 2 and 3 were always significantly cooler (10 to 20 degrees) which made me suspect something wasn't quite right.
