First idea: Take the 140mm fan and rest it on the back of the gpu to huff directly on the mobo vrm heat sink. This will replace air flow that is lost when using a aio loop rather than an air cooler.
Second idea: If temps are really troubling you, go into the bios and switch off 2 cores. Won't impact anything much and can reduce temps so you can use it 'til you've sorted out the cooler. I mean I don't mean you can detach the cooler only that it will bring temps down. for the moment.
Third idea: What thermal paste? Is the the cooler properly attached? Making good contact with the cpu?
Fourth idea: I think you don't have any front intake or rear exhaust fans. Apart from the one 140mm. 2 intake 2 exhaust would be preferable.
What are your cpu temps exactly? Best get a read from AMD overdrive.
This is my
cooler. for an fx Aka. The Thing. Now using bucket of water for a reservoir. Temps are:
Cool. That 34c is with fallout 4 alt tabbed in the background and the 38 is fallout 4 fullscreen. 1200x1600 ultra. Can do 1080p but I can't tell the difference.
Looked up your cooler didn't see the tdp specified on the manufacturer page. The radiator is thicker than most 120mm's but I still don't think it's really enough. The fx is 125w tdp but I'm not sure how much those figures mean. It's a cpu that is a bit on the warm side and pulls a lot of power under load. Estimates range to 220w at default clocks. Which I think means an equal amount of heat.
Generally people have done well with a noctua nh-d15 or a corsair h100i with it from what I've read on the forum previously. But that was for overclocking. Your board has a 6+2 power phase that should be perfect at default but is a bit behind some of the 990fx 8+2 digital power phases so I wouldn't like to say how well it could overclock, probably best not to if you're already struggling with temps.
Also question, brand of psu? A poor quality unit on a 8350 is troublesome.
The scythe fuma rev b benches like the noctua nh-d15 but is more compact at 150mm chassis clearance vs 165mm. The noctua can passively cool in some cases, without the fans running.
At default speeds your cooler should be doing the job so check in the bios that your cpu vCore isn't too high. I'd expect it to be around 1.32 volts at default.
Gpu temps not so hot either what style of cooler is it, blower style or bare heatsink and twin fans ?
I'd be wondering if somehow too much power wasn't going into the system, if the voltages are off somehow but, that isn't exactly my area of expertise. Maybe there are tweaks you can do for the gpu, such as increase the fan speed, or particularly, lower the gpu voltage while staying at default clock speeds. Under volting will reduce temps a bit, if increasing fan speed doesn't do a lot. In radeon settings. Not sure about the under volting thing on a radeon. I'm on a nvidia at the moment.
What chassis are you using? Some folks make a fuss about air flow and all that, I don't bother & leave the side panels off. The Thing is as good a cooler as any. With a mild overclock my system is pretty good for an
fx build overall too. I could rev it up to 4.5-.4.7 but, doesn't really have any huge effect on frame rates, on the heap of ageing titles in my inventory!
Might also venture to ask, when did you buy your system, was a pre-built or did you build it from parts purchased seperately? & how much you paid for it. Since these are the days when fx is obsolete and difficult to get rid of but still I've seen some highly overblown prices on fx builds. My system cost about £250 from parts nearly 4 years ago. £99 board, £70ish cpu (when it was an fx4350) and £50 ram and a few other odds and ends.
I think that you prolly spent too much on the h70 if it's the £109 unit I'm seeing on Corsair's page. The scythe fuma rev b is around £55 and will be adequate for overclocking too.
