AMD fx-8350 stock fan/heatsink idle at 132 F

mjohnson24 · Mar 11, 2016

Im using a cheap case but has 2 x 120mm fans sucking in at front, 2 blowing out the top and 1 pushing out the back. I have the AMD 8350 8-core CPU with stock heatsink and fan that came with it and running at idle, ASUS AI Suite software says its running at about 57c ( 132 degrees F ) at idle. To me thats a little to hot but wanted to see what yall think.
Stock CPU fan running at about 2950 rpm's. If i turn the fan on full blast (5500+ rpm ), its loud but it takes it to ( 113 degrees F ). If i run it full blast (5500+ rpm ) with prime 95 it goes to 141 - 143 F.

What sort of thermal paste are you using? That could impact your cooling performance.

But honestly, you should probably be using an aftermarket heatsink, as stock coolers are notorious for mediocre cooling performance, espeically on higher-power chips like the 8350. Something like a Cooler Master Hyper TX3 would be fine if you're just running at stock speeds, but you might want to step up to the 212 EVO if you want some more overclocking potential and/or your case will fit it in there.

I use a TX3 on my FX-4300, and it runs about 53 C with a stress test running. Interestingly, it reports temperatures around 10-20 C at idle, which doesn't make any sense, but regardless, it can definitely cool a CPU. And all of that is running at 35% speed (~1500 RPM), which is plenty quiet.

Those aren't the only ones you should look at, but they'd definitely be a good place to start, especially if cost is a concern, as they're pretty budget friendly. The TX3 is under $20 and the 212 is about $25. But be careful with the 212 EVO, as some cases, including my brother's, aren't quite wide enough to admit that cooler.

The case im using is a cheap case since its a work PC at the company i work for so its not for gaming but i do use it everyday for stuff and it will potentially be a automatic music editing server. The case im using is a DIY D480-BK which has 5 120mm fans in it. not sure what the clearance is from CPU to side of case is.

SirDoctorK · Mar 11, 2016

mjohnson24 :

Probably safer to go with the TX3 or similarly normal-sized heatsink. Assuming, of course, that your company is OK with you tinkering with the computer they provide. The TX3 has more than enough cooling power for the FX-4300 I'm running, so I'd expect no problems cooling an 8350. And the much larger fan is capable of moving a lot more air at lower RPM's.

In fact, I found a video comparing stock to TX3 (note that it's the same chip, but overclocked): https://www.youtube.com/watch?v=MH9Oj_g6xYU
Here's another comparing stock to 212: https://www.youtube.com/watch?v=X53Zdsm4UWA

With that said, I'd look elsewhere for similar tower heatsinks. And, while you're at it, measure how much clearance you have, as you might be able to fit in a 212. If sound is a priority, you may find Be Quiet!'s offerings to be a nice option. Keep in mind that sometimes, tower heatsinks can have problems fitting on a motherboard while still allowing access to RAM slots, power/fan connectors, etc. With my TX3, the fan housing makes it a bit tight getting the closest RAM DIMM in and out, but it's still doable.

And finally, you may want to also invest in some decent thermal paste. I saw 10~20 C improvements in load temps on my R9 270X after replacing the stock thermal compound with Antec Nano Diamond Formula 7.

SirDoctorK :

with the antec nano diamond formula 7 is it easy to get the CPU Cooler off th CPU if u need to change it in the future or something? AS for the 212 evo i think it will with enough clearance. Close but i think it will fit. But my boss is ok with me tinkering with it and hes ok with getting a better cooler. im he one that put the system together on newegg and built the computer so its no big deal but we may build a server that will run an app that we had built that mixes audio for us that will work the CPU for sure so the cooler we can get it the better and since mine is the one thats gonna be the beta tester for it to see how it performs we need to make sure it stays cool in good temps under a heavy load. If it stays under good temps under a prime95 load with all 8 cores then we are good. But as of right now 143 degrees F is a little to close for comfort for my likings. But i think a 240mm liquid cooler would be overdoing it but i think a single fan liquid cooler would be ok too and hes ok with it as long as we get it to good temps under a heavy load. the board im using is an asus 970 pro gaming with 32gb ripjaw x ram (4) 8gb sticks. According to DIY they say it has 159mm clearance for a cpu cooler

watched those videos. Thats crazy. That noise level is exactly how loud mine is. Cant believe AMD would even send that crap as stock with an 8 core CPU.

That's actually a pretty nice looking work system. Plenty of air moving through that case. And since it looks like a relatively current case aimed at system builders, the 212 is fairly likely to fit. And, of course, it's pretty cool that you're using a custom rig as a work computer.

IMHO, liquid cooling would be a bit overkill, especially if you have no plans to overclock. Especially since an entry-level AIO liquid cooler is rarely going to outperform a mid-range or better air cooler, yet it'll cost much more.

Formula 7 seems to stay fluid after being installed, so re-seating it further down the road should be no problem. I put that stuff on my old video card, and just recently re-seated it again after it sat in an anti static bag for several months. Although an even more compelling example would be my CPU, as it's been seated with what I must assume is Formula 7 for probably a few years now. But I'm in the middle of other stuff, so I can't really go re-seating the heatsink right now.

yea my old one was a few years old so my boss/cousin told me to put one together and get it ordered. I didnt splurge alot but i dd get it with a 1tb ssd drive and an decent 2gb radeon video card and an 8 core cpu. But yea the liquid cooler might be a little over kill but the computer that will be identical to mine if it works out will be running 24hours a day 7 days a week constantly mixing audio files and such so i just wanna make sure its gonna stay cool consistently under a heavy load all day all week for the life of the computer or its time to upgrade again.

SirDoctorK · Mar 12, 2016

mjohnson24 :

I'm thinking more and more that (provided it'll fit) the 212 would be a great choice. There are certainly better coolers out there, but they'd be a lot more expensive, and most likely, just plain overkill for a stock or even mildly overclocked FX-8350.

mjohnson24 · Mar 12, 2016

Im eyeballing the Hyper 212 evo, 212x and 212x dual fan and the NH-D14. I like the CM TPC-812 but they dont have the $96 and the other is almost $160. But my main reason for that one as well as the others especialy the dual fans are that they wont clear my Ripjaw X ram. I dont wanna buy em and find they dont clear em now i gotta pay a restocking fee.

On another note as far as overkill i am for sure ok with overkill. If liquid cooling would cool it better than a hyper 212 or any air cooler then i will go with that. This computer is gonna be running constantly 24/7 so it may not be OC'd but it will be a work horse in other regards. What liquid cooler would be comperable or better than the air coolers? I know many youtube videos show people using the hyper 212 evo or the hyper 212 x so i know its a good choice but wanna have a good choice of liquid coolers also.

SirDoctorK · Mar 13, 2016

mjohnson24 :

I actually have zero experience with liquid cooling, but I can tell you for sure that liquid cooling will eliminate any problems with RAM clearance. And I've heard good things of the H100i. But regardless, I'd try to go with a dual-fan radiator, since you have room for one, as single-fan radiators seem to perform about as good or worse than a similar air cooler. But keep in mind that something like this would set you back ~$100+, where a single-fan radiator would be around $50~80.

Here are some videos about air vs liquid cooling:

mjohnson24 :

Yea i know RAM wont be an issue as far as clearance is concerned with Liquid cooling. Thats the one i was looking at is the H100!. AS for the cost im not worried about myself and i dont think my boss will be worried either as long as it brings my temps down. the link below is a screenshot as of right now. I remoted into my Work PC and its been idle since friday and this is what it shows in ASUS AI Suite. And the other link is to a pdf of what i bought. Its not the best but for a work PC it works goo dfor what i need it for except for the processor not cooling like it should.

www.skycloudphotography.com/workpc/Capture.jpg
www.skycloudphotography.com/workpc/WorkPC.pdf

I also see that there is a H110i GTX, H105 Extrreme, H100i GT, H110 extreme, H100i V2 Extreme, H100i GTX Extreme, H115i Extreme, H110i Extreme

I know you said your not an expert but does anyone know whats the difference or which is the best or would be good? I know this isnt a gaming PC and it wont be overclocked or anything of that nature but just want something that is gonna have no problem cooling this PC and wont worry about ram clearance and wont sound like an airplane taking off when the fan (s) are running. Does anyone know about any of these liquid coolers? Which one would outperform the Cooler Master Hyper 212 or 212x air cooler? I hear good things about that air cooler that it would work too and thats my air cooled option but want a liquid cooled option to go to my boss about. And are AIO's safe as in wont leak like a custom water cooler system will?

What would be another air cooler that would be as good or better than the Hyper 212 or hyper 212x? One that would or should clear my ram sticks.

SirDoctorK · Mar 14, 2016

mjohnson24 :

As long as you're careful with your handling and installation of a liquid cooler (particularly with the tubing), leaks would be very unlikely. Possible, and potentially catastrophic, but very unlikely. Liquid cooling is a bit riskier than air cooling, as the fluids have the potential to leak out and cause major damage, but modern hardware is designed pretty well, so the chances of it happening make it a moot point for a lot of people.

Frankly, I think I'd go with whichever of those options would be the cheapest. At this point, they're all going to provide more than enough cooling (as long as their all dual-fan radiators), so unless one of them offers a feature that you really like, it's probably not worth the extra cash.

Clearing those RAM sticks could be a problem, as those G.SKILL X series heat spreaders are pretty sizeable. But I was able to find a number for the 212 EVO's RAM clearance. From the part that rests on the CPU to the bottom of the fan is 37 mm (source: http://www.coolermaster.com/cooling/cpu-air-cooler/hyper-212-evo/). If you measure how high the RAM is in your system from the bottom of the current heatsink, that should tell if it would fit. But keep in mind that on your particular motherboard, it might not even extend over the RAM slots.

Andrei-Florin Gogan · Mar 14, 2016

Could you list us the parts in the computer? AMD CPUs especially FX chips are a bit complicated when reading the temperature. AMD Overdrive is the only one that can accurately read the thermal margins. Normal temperature readings are very inaccurate with AMD CPUs. Keep in mind that reading the thermal margin works in reverse with a cap of 72C. The higher the thermal margin the cooler the CPU actually is. The stock AMD cooler is a no go with an 8 core CPU. It works as intended but is very bad compared to the 212Evo that you want. The CM 212Evo is quite tall and you will need to find out the exact model of your case. I suspect it is the Aerocool Aero 800 in which the 212Evo will fit but I may be wrong so double check and let us know.

madmatt30 · Mar 14, 2016

With 4 sticks of ram most tower coolers will have problems clearing the closest stick (the 212 series definitely will)

Ergo , for starters I'll recommend the Pallas which is supremely quiet & performs on a par or slightly better than the evo.

http://pcpartpicker.com/part/raijintek-cpu-cooler-0r100012

For towers pretty much the only one that is guaranteed no ram interference is the cryorig h7

http://pcpartpicker.com/search/?cc=us&q=cryorig+h7

120mm aio's - you'll be doubling the budget to match either of those & a 120mm rad setup will be noisier if anything.

Yea they may not extend over them or even touch em hah? So i might be good with a 212 evo and get a second fan kit for it to do a push pull effect. I think i got 159mm clearance according to the case manufacturer's specs to the side of case. I was going to go with a Noctua NH-D14 but supposedly its like 169mm tall.

madmatt30 · Mar 14, 2016

The evo will definitely hit your ram mate & you font have the height clearance to push the fan up to clear the heatsinks .
Go with the h7 instead

mjohnson24 · Mar 14, 2016

madmatt30 :

CRYORIG H7? it wont hit my ram at all? It looks as though in pics on newegg site its built a little off center a little. Is that a good fan/heatsink? just as good as the 212 evo? Will it cool the FX-8350 8 core cpu really well as you can see in my screenshot of my temps at idle its high. Is the single fan good or should i do a two fan push pull effect?

madmatt30 · Mar 14, 2016

^ absolutely , the main sink is offset 20mm back from the base purposely to allow ram clearance even on matx boards.
Its also incredibly squat at 145mm.
That's why it's known as the h7 universal - it'll fit in just about any case that isn't low profile.

Cooling wise 5-10c better than the evo - $10 more but a no brainer really IMO.

mjohnson24 · Mar 14, 2016

madmatt30 :

That one sounds like a good winner. I just want something that will keep my CPU cooler at idle. The temps its at now should be under a load not idle. Ill talk to my boss about it. I wanted to go with liquid cooling but hear people talk about 2 yrs or so life expectancy and plus some say they can leak. Something i might look at if i had the FX-9590 for personal or something possibly but think im going with an air cooler for work. Now im wandering if i should replace the fans with some that will push and pull air in and out of the case more. Im sure since this is a cheap case that the fans are cheap and i have 2 in front sucking in, 1 in back sucking out and 2 on top sucking out. They came with the case that way. according to the website it looks to be a really good cooler.

madmatt30 · Mar 14, 2016

Cheap case fans tend to do enough IMO.
What you find normally with quality case fans are a difference in noise rather than actual cooling ability vs cheap ones.

Regarding idle/load temps , a guy mentioned this before but really you should download amd overdrive & check the thermal margin in that.idle temps are always unreliable on any fx chip - there is no actual temp sensor on chip.
Idle temps are worked out by an algorithm & ultimately only amd overdrive will get close to any kind of accuracy

Short test.

madmatt30 · Mar 14, 2016

^ those temps are very very good mate in all honesty.

Equates to 30c idle /50c prime load or thereabouts.

The monitoring software you were using is inaccurate IMO.

The h7 will drop 10c off those temps while running close to silent.

mjohnson24 · Mar 14, 2016

madmatt30 :

Thats only running for about a couple minutes is all. I might still get the H7. I like the R1 universal but its 168+ height i dont think will work for my case.

The below is running for about maybe 10 - 20 minues or so maybe a little less not sure still running Prime 95

www.skycloudphotography.com/workpc/Prime95.PNG

I didnt think about the cooler clearance. I shoulda have figured out what case would work best for tall coolers for clearance and got it instead and maybe looked at the shorter ram sticks.

mjohnson24 · Mar 14, 2016

side question. Whats the best cooler out there to cool an FX-9590 on a ASUS Crosshair V Formula Z board and what ram would i need to get to make sure the cooler would fit?

again how tall isnt a concern. I plan on checking out the HAF X case which i ned to see what the clearance is for the height of coolers but still whats th best cooler for that CPU since it runs at 225 watts or so?
