I currently have an FX4300 in my mobo with the standard Heatsinkfan. I have been looking at an 8350 which I believe had a wraith cooler, but unfortunately not! If I can pick up a 8350 CPU with lesser cooler for £85 or the Wraith version for £115 can anyone think of a cooler that's better for the difference? I'd like one that blows on the mobo btw?! Plus if anyone can tell me of a better CPU that'll go in the board please let me know, the mobo's 140w
 
£30 will get you a reasonable air cooler. The Wraith is ok but £30 is multiple heat pipe territory. Not sure about blowing down though, might be better to use a case fan for that. FX-9590 is the highest spec AM3+ CPU far as I know but it is one thirsty, hot chip. More trouble than it's worth even, considering the platform is quite dated.

I've heard of more power/heat stability issues with the 9590 that any other CPU.
 
Got decent side air flow, it's an olds school Cosmos S, granted the big arse fan runs far slower than I'd like to cool the mother board. The 9XXX seems to have ridiculous power requirements for the MHz extra! That's why I'm looking at the 8350.... anyone got any better ideas? No offence to my friend who already responded, btw, which Heatsink would you recommend???
 
My case is massive! lol, It was only the price / board cooling I was worried about! Is that a good cooler?! I got given a LOKI SD963, which on face value should be the same.... but I doubt it!

Oh, btw, its in the box , never used it!

The 8350 and 9590 are basically the same CPU. I have had both. My 8350 could achieve 5.04GHz and I ran it at 16 x 300MHz = 4800MHz 24/7. The 9590 achieved similar clocks at similar power demands.

Notably the cinebench R15 result at 5.04GHz was 803 for the 8350, I am now running a 1700 Ryzen at 3.7GHz and I get 1640 in Cinebench ie >100% larger at a lower clock speed.

I used a large thermalright cooler, you could get a second hand one for about £30. I would try the Loki.

even this, cheapest of ryzen cores and B350 boards would smash the fx4100

My basket at Overclockers UK:
Total: £233.43 (includes shipping: £10.50)


for extra £100 over fx8350 and cooler- worth it - specially if your able to go deeper for £120 ryzen 1400!!!​
 
I’ve seen 8350s for sale around the £50 mark, you might say that was worth it to squeeze a bit longer out of it. Any more though and you may as well put the dough towards a new platform.

However I would say the Extreme3 is really going to struggle supplying the sort of power a FX 8350 needs.

If I could find a REALLY cheap 8350/9590 etc and had a board good enough to run it I might consider that before making the leap to AM4 and DDR4.

What is it you’re wanting to do that the FX 4300 is struggling with?
 
To be honest, it's not struggling! I'm just looking to upgrade mine a little so as I can pass the FX4300 down to my brother who currently has a Dual Core (270 I think).
 
Fair enough, like I say it might be a worthwhile upgrade if you can find one cheap enough. Just don't pay anywhere near £100 for it. As i said though the VRMs on that board will be struggling a little with it, you mentioned you wanted a cooler which blows downwards on the board and that'll help but really you could do with finding a way to improve airflow to them without using hot air from the heatsink
 
As already mentioned, that board is a 4+1 VRM setup which will cause you issues on an 8 core fx.

I spent a while messing with one and achieved 4.5ghz stable with an 8320 but its critical to have active cooling on the VRMs otherwise you will hit some very unpleasant throttling. I went for a 6cm fan suspended 5mm above the VRM heatsink and a 212EVO and it worked great.

Dont buy an FX CPU new/full price though!
 
Currently all my fans, the big side one included are hooked up to a hub governed by the CPU header. I dare say I can run it at full tilt without a lot of noise. The board is rated at 140W max, which should be enough... I'm not planning on overclocking!

My board, and there seem to be a few with the same name, just to be confusing is the FX990, rated at taking up to a 140w CPU, is this still the one you were looking at? http://www.asrock.com/mb/AMD/990FX Extreme3/
 
Strangely enough I've still got that model FX990 sitting on a shelf since I upgraded to a Asus Crosshair 5 formula Z.

What I originally wrote was about the 970 but I also spent a fair amount of time messing around with the 990 as well.

In my experience the 990 has marginally stronger VRMs although it retains the same 4 + 1 setup. It can run an 8 core processor without issues but under sustained load the VRMs will overheat and the system will throttle the CPU back until they have cooled, which normally takes 5 - 10 seconds. If you put a fan over the VRM heatsink it will prevent throttling in any scenario other than deliberate attempts to punish them (eg: Prime95) at reasonable overclocks. You can see the throttling happen in real time by using HWmonitor and observing motherboard tmp 1 and cpu clock.

FWIW I think the FX CPUs got their bad rep from people not really understanding the role that VRMs can play in CPU performance. GPUs have definitely made people more aware of power deliveries effect on stability and performance though.
 
Thanks for the response and info! My plan is still to get an FX8350 when I can find one for a sensible price (cheap!) I'm only running dual 1080 panels and it's not like I'm video editing so there's plenty of life left in this old horse yet. Thanks again.
