AMD Fx 9370 Heat issues

xFuchs23 · Oct 8, 2016

Okay, so I have just recently started running my Fx 9370 again. The AMD pump that came with the CPU when I purchased is bad, so I'm using a stock AMD heat sink and fan. (I know this is no where near what I actually need) HWMonitor and Open Hardware Monitor both say that my idle temp is around 48C-50C, but the more I search the more different answers I get, so I have a few questions: What is normal idle temps for this CPU? What is max temp that won't damage my CPU? (I have heard 61C and 80C)Would I be okay to use this heat sink until I can get my hands on another? If this is unsafe, how would I under clock my CPU to around 3.5GHz? Any other suggestions are welcomed
-Thanks so much for your suggestions/answers and time, means a lot.
Also, if this is already a post, I apologize, I have gotten so many different answers that I just want to make sure.

No, using a stock heatsink is no a good idea for that processor.
The general consensus is ~62C, 80C is aimed at intel processors.

Underclocking is a viable option until you can get adequate cooling.

I have seen 80C on a few different forums for this CPU and I've seen 60C. The hottest I have seen it is 62C and that was while I was running Ace of Spades which is pretty much nothing to run. I know that at 97C it damages the components inside the CPU, so why wouldn't it work to run at 80C, just curious, not doubting you.

The 97C does not sound right, typically only GPUs can operate at those temps, and even then its not good.
Since AMD does not release official numbers like intel does (its right on their product pages) its more of a communal number.
At around 63C the processor is supposed to thermal throttle to prevent damage, AMD processors simply are not designed to operate that high.

Also, currently my CPU in both programs is reading about 5C, and I have restarted both. I am thinking that this is because the thermal paste wast completely spread and now it is? I'm not completely sure

AMD processors are notorious for reporting false temps under low levels.
What does AMD OD say? That is one of the most accurate ways to measure AMD temps, via the offset method.

I agree with the underclocking part, if you can go into your mobo bios underclock it to 3.4ghz which will be default for now.
Set the over clock speed to 3.8ghz, if done right that should keep you steady for atleast a month or two at best.
Also you may need to reduce the memory speed to get this achieved.

AMD OD says ~40C idle. Do either of you happen to know how to flush the AMD water cooler and put new fluid in? I haven't checked it out much, but the propeller inside the pump is ticking pretty bad, so I was going to flush it out and put new liquid, but I have no idea how much to add or what the liquid is called.

Gam3r01 · Oct 8, 2016

Its a closed loop cooler, you cant add or remove liquid to it, doing so ruins the cooler as a unit.

xFuchs23 · Oct 8, 2016

I'm a senior at a vocational school and I asked my Networking teacher about it and he's the one that recommended it. Mind you, he has been teaching for 15 years now.

Gam3r01 · Oct 8, 2016

You can do it if you want, but I dont exactly see what a Networking Teacher is going to know about refilling a unit designed to be factory sealed.
CLCs dont use water, they use a special coolant, so you will need to purchase that, find a way to drain whatever is still in the loop fully, you cant be mixing liquids here, then you will have to figure out how to reseal the loop with an adequate amount of liquid (which is how much? Well nobody knows) and keep the unit sealed once its opened.

There are many people who have sought to do the same, CLCs are designed to stay closed, they are not open loop coolers for a reason.

xFuchs23 · Oct 8, 2016

The pump is bad regardless, so it doesn't hurt to try. I understand everything you're saying, but I had it apart the other day and the "factory seal" is nothing more than a rubber O ring and it hasn't leaked thus far.(Then again, I'm not using it) I do understand what you saying, though. Whenever I try this, I'm going to test it outside the PC and check for leaks and everything, I just didn't know if you guys have ever tried or done it.

xFuchs23 · Oct 8, 2016

Also, the special coolant is a mixture is water and ethanol glycol.

xFuchs23 :

Leave well enough alone and listen to Gamer1, even though I've never used a water cooler before.
I don't think its a wise idea to mess with a closed loop water cooler.

Those two items combined together and with your cpu clock speed at 4.2ghz or or 4.4ghz.
That should keep it cool for atleast 6 months straight or longer before needing to change out the grease again.

Last night I took the pump back apart, drained it and filtered it to get the gunk out and now it works fine. I used a coffee filter to filter all the liquid through and then put the liquid back in. I had to use a little bit of water to replace the drops that came out of the pump, but so far everything is working great. No leaks or anything

Ecky · Oct 9, 2016

Was the pump's problem that there was crud built up in the loop?

xFuchs23 · Oct 9, 2016

There wasn't much, but yes. I do understand that there is a problem somewhere that it's chipping,but it's almost like it was paint chips or something. I'm sure I'll eventually be cleaning out out again or buying a new unit, but for now it's working great
