I have been updated my old computer.I bought Sabertooth 990 R2 and a 1000W PSU with 2 7870 crossfired. But i'm still using a old Phenom II X4 955 and i want to update to FX 9590 (i've been saving some bucks). 

My cooling system is a Corsair H70core and keeps my old Phenom II X4 955 cool, but ... Would it be sufficient for a new FX 9590? 

 

Thanks from AMD fan!

Yes, but save yourself some money and get an 8350 instead. It's $100 cheaper and can hit the 4.7ghz the 9590 can with little to no voltage increases.

But FX 9590 is a 220W ... how does the Corsair H70 core perform ?... Sure?

Is better than your H60 or not? What about your working temps?

None of the Corsair Hxx models are very good coolers as extensive testing by many sites have documented. The absolute minimal Corsair H2O cooler that I would recommend for an 8-core FX CPU is the H100i. It will probably just be enough for the FX-9590 with little margin when your CPU is 100% loaded such as in stress testing, P95, serious encoding or long video game play. The Swiftech 220 would be better based on test results.

Most people don't realize how thermally inefficient the Closed Loop Coolers, (CLCs) are until they spend their money and see the end result. A PII processor has a much lower thermal load compared to an 8-core FX processor, especially the FX-9000 series which are just factory overclocked FX-8350 CPUs. The really bad issue with CLCs or H2O cooling is the system damage that occurs when they leak - and they do leak sooner or later.

As far as the FX-8350 vs. the FX-9590, I agree that the FX-8350 is the better CPU if you have the expertise to do simple overclocking. If not then you can buy the FX-9590 but you must use it on an AM3+ mobo that specifically supports the FX-9000 series CPUs. There are only a handful of mobos that properly support the FX-9000 series.

Asus says that your mobo can run the FX-9000 model CPUs if you use the proper BIOS and cooling. The H70 is no where near enough cooler for the FX-8000 or FX-9000 series CPUs.



-------------------------

Building a reliable PC involves more than just assembling the parts. You need to be able to configure all of the BIOS settings appropriately. This can be quite involved and frustrating as it can require a lot of trial and error with stress testing. It is however often the only means to get a 100% reliable PC.

Can i use my Corsair H70 core on a single FX 8350 at 4 Ghz (not overclocked)? ...

... It performs superb on my old phenom II X4 955 overclocked at 3.8 Ghz ... max temp at full load 60ºC ... idle 38º (temp amb 25ºC) 

The max TDP of FX 8350 is the same or less than Phenom II X4 955 overclocked (aprox 130 W).  I reckon that Corsair H70 core would be more than enough on a FX 8350 non overclocked. 

What is the maximum safe temperature of FX 8350 at full load ? 60ºC? 70ºC?

 

PD : My old Phenom II X4 955 BE was working at 75º C for 24/7 during a year stable ... and it is still doing fine in the new mobo but at 33ºC ...

I use my H60 with two fans in push/pull on my 8350 on my FX-8350 at 4.6GHz and it only hits 55°C in Prime95.

I think i will go for a FX8350 and try to overclock it with the sabertooth 990FX R2.

The TDP is the same 125w but the 8-core CPU still consumes more total power. TDP is total design power, not total power consumed.

The H70 might work depending on how hard you run your PC. Since you have it you could try it without a cost issue. I don't recommend any Corsair H series or similar CLCs because of the inferior thermal properties and undeniable water leak liability compared to a highend HSF. Since you have it, you might as well try it. You can always change to a better cooler if you need it and you might.

The max 24/7 FX-8000 series core temp is 61C. You will likely see issues in the mid 60's and the CPU is throttled at 70C so you definitely don't want to be much if at all above 61C for system reliability reasons.

Ok the CLC don't leak unless you damage them somehow, and a custom loop if properly built will only not leak but be alot more efficent than a HSF. Its all in how you do it.

 

I'd suggest if your going to use liquid cooling to build your own loop, a 240 rad, a good cpu block, a well rated resivor, a good pump, a silver kill coil and good tubing, and then just buy distilled water. I know I'm planning on going water on this FX 6300 here shortly but I have parts left over from my previous water setup, my 360 rad, my 6 yateloon fans and ive still got 5 feet of tubing, all I need is a new resivor/pump and a water block.

AMD Athlon XP 3200 -- ECS KT600A -- PNY Geforce 6600 -- 2gb DDR333 -- WD 80gb

H2O coolers all leak sooner or later. The CLCs just seem to leak sooner and more frequently. Corsair changed manufacturers for the new "i" series due to so many leaks with the former non-i series.

A true open loop H2O cooling system will cool better tthan the CLCs but an entry level open loop system starts at ~$195. Since these systems offer no performance benefit other than for extreme overclocking, they are not practical for most folks and they always have the leak liability waiting to destroy expensive PC hardware.

Unless someone actually has a need for an H2O system, I highly recommend against them because the CLCs are thermally inefficient, noisy and expensive compared to a quality, highend tower cooler.

That being said, IMO people should educate themselves on the technical facts regarding coolers and other PC hardware and then buy what makes them happy. It's your money and your decision. As an educated consumer at least you know what to expect without all of the hype and fanboism that is often used to sell inferior CLCs.

In the OP's case if he didn't already have the H70 he'd be wise to just buy a quality, reliable HSF and be done with it. But due to the fact he already has an H70 it's worth giving it a try to see if it has enough capacity for his use. He'll still always have the leak liability but he seems willing to accept that risk, so he's got nothing to lose by trying it on the FX-8350.

I definitely would NOT recommend an expensive open loop H2O system to anyone who doesn't plan on extreme overclocking with a chiller. It's pretty pointless when for $70 you can have a quality HSF that provides all the cooling necessary for an 8-core FX CPU and zero water leak liability.
