Hi,

I upgraded from an fx4300 with an Akasa AK-876 HSF to an fx8320 and an Arctic freezer 7 Pro. Asus M5A97 R2.0 Board.

I'm having temperature issues and looking to upgrade to a Cooler Master Hyper 212x HSF. My temps are low to mid 40's idle after bootup with nothing loaded.

With up to 25 browser windows open and a couple of office apps, CPU utilization at between 4%-35% (it spikes up and down a LOT, this is another issue that was there before my CPU upgrade. It is averaging 20% at the moment while I'm writing this post), my CPU temperatures are rising up to 49-54 deg with the CPU fan and the case fans @ 50% speed set manually using Asus Fan Xpert. Ambient room temp is 17-20 deg. The motherboard is at 31 deg.

1300rpm on the CPU fan, 700rpm on the case fans getting c. 50 deg on the CPU. With the above programs open. I also have the Akasa fan from my old HSF taped to the top of the heatsink of the Arctic Freezer sucking the air out. It runs at 1400rpm I don't know if it is doing any good, but heat is rising out of it as it sucks. These speeds keep the noise at a tolerable level for now until I get better cooling.

If I were to start watching a Netflix movie in a window it will jump from say 49 deg to 54-55 deg.

Right now it is at 15% CPU use and 50 deg c.

If I load more programs, bringing it up to, say, 60% CPU utilization I struggle to keep the CPU temperature below 55 deg.That is with all the fans turned up to 100%, which is very noisy indeed.

I have x4 Arctic F12 PWM fans, x2 front intake, x2 exaust: x1 at the rear and x1 at the top of the case.

My old 4300 CPU could run at 95% utilization with the fans at 55% speed and 55 degrees on the CPU. I can't run any more than 25% of the apps and browser windows that I would normally before the upgrade. I used to run 120 browser windows and 20-30 applications no heat problems, except it was maxing out the CPU.

I don't game much, the only 3d I do is Second Life, and watching Nvidia demos, but I do use a lot of different programs at once. I thought I would be able to run even more with the 8320 as I was maxing out the 4300. That's why I upgraded.

AMD Overdrive reports an average of 35 deg of Thermal Margin @ 50 deg CPU temp. it fluctuates between 27 and 38 deg. Why is this margin so high as I am only 12 degrees below the 62 deg limit on the fx8320 ? I'm VERY paranoid about burning out the CPU if I go above 62 deg.

Is it advisable to switch on Cool & Quiet in the BIOS ? Should I switch off the Turbo boost ? Would this just make the CPU work harder and not solve any of my current temperature problems ? CPU speed seems to stay at 3.7 Ghz all the time. I have no plans to overclock the system. I like to run at stock and stable.

I also think I need to replace the PSU. The Corsair CX600 isn't a good PSU, and it has developed a "Coil Whine" after the upgrade. Although it may have been there before, perhaps I just didn't notice it.

Thanks for taking the time to read my post,

Onomatik.

I have the 212X and is great but not for that processor, I bought a 612v2 and used the 212x fan for it, I got way better temps, but still high under heavy load (overcloked), so you need something better, maybe water cooling not sure, but it would be the best.

I would recommend keeping the CPU just under 65C if it goes up it can cause stability issues that voltage can't fix, but only worsen.

If your cooling method can keep your CPU under 65C in Prime 95 you can be a happy man, that means under 60C in most common workloads, even some light gaming, and as far as I know the 212X is not able to achieve it, your CPU is not going to burn, but it will reach around 68-70 (depending on your ambient temps), which is not good enough.

In AMD overdrive all the readouts are fluctuating up and down rapidly about once per second. I switched the power plan in windows from Performance to Balanced, that cooled things down about 3 degrees @ 7%-18% utilization. I also switched off turbo mode using AMD overdrive. That dropped it 1 deg. The Voltages are fluctuating fast between 0.925, 1.165, 1.275, 1.375. The maximum I've seen is about 1.425v. The utilization is at 20%-30% When it decides it needs to ramp up the clock to 3.5Ghz .

The clock varies between 1.4Ghz and 2.3Ghz rapidly when utilization is low, as do all the readouts in AMD overdrive. What would I do to modify the Load Line Calibration ?

Thanks,

Freezer 7 pro is nowhere near good enough for an 8320 mate.
& yes you should definitely have c&q enabled , there is no reason to disable it whatsoever unless you are on a quest for monster overclock.

Disabled is detrimental to both CPU temps & voltages at low/idle loads.

Yeah, I've come to the conclusion that the Freezer 7 isn't anywhere near good enough too. I honestly thought it would leave me with temps similar to my old setup on my FX-4300 with the Akasa AK-876. I had no idea that 8320's got so HOT. I almost bought an FX-8320E for cooler running. I'm not into overclocking, I just wanted a bit of a performance boost upgrade from my old quad core CPU. *sigh*. Anybody got a TARDIS ??

I'm thinking about ordering a Cooler Master Hyper 212x. I'd go higher, but I'm on a budget.

Cheers,

Onomatik.
 
amd overdrive says your cpu temp is fine. you cannot go by the cpu temp reading as it is just a sensor near the cpu it is not in the cpu die. amd overdrive reads the temp of the die. as long as your thermal margin is not near 0 or negative your ok. all your numbers look normal. and your new cpu will run hotter as it has more power draw then your old cpu. 62c isn't much (only 140F) don't know where you got that this is its limit. these cpus will run up to closer to 80c (176F) before they really are considered at there temp limit.

Cooler Master Hyper 212x is an excellent cooler for its price with multitude of good reviews.

You can honestly run the CPU hotter with no worries ??! I found out a short time ago that the Tj. Max for the CPU Was 90 deg C. , but all over the web there are cautions about running it above 62 deg, e.g. a post from Tom's hardware:

"Max safe core temp recommended by AMD is 62 degrees celsius.
maximum socket temperature is 70 degrees celsius.
its best to keep the core temperature under 55 degrees though to keep the lifetime longer."

And other posts here, and in other places.

To understand this I could run the chip at, say, 65-70 Deg C all the time and not worry about burning it out, throttling down, crashing, it turning into a bowl of petunia's or a sperm whale ??! It hits 58 and I'm reaching for the off switch/fire extinguisher. Wow.. I'm learning things. Honestly, I can relax a bit ??
