PC Processors

[lojikal]

Hello fellow AMD users. I'm urgently in need of some help. I recently purchased a boxed AMD FX -  8350 which was advertised to include the AMD Wraith Cooler. Upon receiving the package one of the things I immediately noticed was the cooler was not the AMD Wraith Cooler but instead the AMD SILENT COOLER without LED light Socket FM2/FM1/AM3/AM2+/AM2/1207/939/940/754 Copper Base/Alum Heat Sink & 3.5" Fan w/Heatpipes & 4-Pin Connector Up to 125W. I immediately contacted the seller via Amazon messaging system to express my concern and disappointment. The seller was quite polite and after apologizing sent me an AMD Wraith Prism cooler as a replacement. Now here's my concern. The TDP rating on the AMD SILENT COOLER IS 125W, however the TDP rating on the WRAITH PRISM is nowhere to be found (most websites simply state that it's suitable for processors with a TDP rating of 105). Agreeably this doesn't specify the TDP rating of the cooler itself. I am quite concerned that installing the WRAITH PRISM with my FX-8350 will cause the processor to operate outside it's allowed temperature range subsequently shortening the life of the processor.

I would genuinely appreciate any advice based on your expertise.

Thanks in advance,

Kreyg Scott

Please see images of actual cooler included in package.

You should keep the originaliteit boxed cooler, or talk to the seller again explain that after looking in to it you realised that the wraith you've recieved is meant for ryzen 1000/2000 (maybe 3000 too) 

Ask if he would consider upselling you to a aftermarket (coolermaster 120 evo/something tower) at a discount (with returning both of the coolers ofcourse)

Though i dont think wraith would be be overpowered, if you have no choise: set throttling at 75'C and undervolt vCore as much as possible and do not OC! 

If the wraith doesnt keep up, it might boil the heatpipes dry and the whole thing & cpu will quickly get really hot. 

You can kill the CPU with an underspec'd Cooler .. it probably wont happen but it can happen.

You've got a point. I'm thinking of just asking for a refund for the cooler and investing in a Noctua NH-D14, Premium CPU Cooler. I checked the clearance of this cooler with my CPU case and it will fit.

That would do.. be sure to check for am3+ mounting brackets and remeber to use the backplate. Its heavy so better safe than sorry.

Good luck

When I purchased my FX8350 with CPU Cooler was the same one you received - the Non-Wraith CPU Cooler which lasted for several years kept my CPU without overheating before I needed to replaced it with a Coolermaster Hyper212 ECO CPU Cooler.

Yes it seems like the Wraith Prism does have a 105 watt TDP ratings which is sufficient for most Ryzen CPUs TDP ratings that comes with the Prism bundled.

If you still have the original 125 watt TDP rated CPU cooler that came with your FX8350 I would use that instead of the Prism.

The FX8350 maximum operating temperature is around 61c so you will need a strong CPU Cooler to prevent it from going past 61c.

NOTE: I wouldn't worry about your CPU life span being shortened. That happens if you run the CPU past 61c constantly for a long time. The more your run the CPU past 61c like above 70c then most likely it will shorten the life span.

Leave it to @elstaci to know the exact CM 212EVO tower i meant.  

Btw1: 2 fans mounted or one?

Btw2: 61'C .. no way, at 100% load @stock it would reach about 70~75'C..

Even my old 8120 goes to 80'C with ease and i though max was set as high as 105'C. I agree that it will cost you lifespan, but 61'C .. i faintly remember the default fan profile on my asrock just touching 50% fan at 60'C but 100% at 75'C..

83xx was designed with longer pipelines and more spread-out die lay-out vs 81xx. It was designed to run a higher clock, at cost of power consumption, and longer pipelines (and thus lowering ipc + increased latency, when a cache-miss occurs) .. Point being: it was build to get hotter, as the uarch needed clockspeed to counteract the FP-unit presure, caused by intel switching compilerstrategy to suddenly so programs would use FP instead of INTEGER/MMX. 

My 8120 ran circles around a i7 2600k in some tests on Linux, but also got equally dostroyed in others.. until the shift in Intel compiler)

8 cores with 7,6x 1c performance was incredible scaling ... 4c/8t i7 through HT did not scale as well .. though FP units are half the ALU units .. so FPU wise it was more like 3,8c vs Intel 4c/8t FPU.

FPU cores were stronger/faster, not nearly twices as fast... 

Just realised im taking this way off-topic

I needed to mount 2 fans. But one of them was a High CFM Fan (5000 RPM) in a Push Pull configuration on my CM Hyper212 EVO CPU Cooler.

You can try with one to see if it keeps the CPU below 61c during normal or heavy uses.

The FX8350 is a hot running CPU.

By the way, I am now using the same CoolerMaster CPU Cooler for my Ryzen 7 3700X with no overheating issues.

The FX8350 I used to upgrade my wife's FX6350 CPU on her IBUYPOWER PC with another cheap 150 watt TDP Air CPU Cooler with also 2 fans. Thou I did need to modify the inside of the PC Case to get it to fit properly.

EDIT: We both were responding to the thread at the same time originally because I didn't see your reply until now.

I'm not OP .. lol .. i didnt go for 2 fan, as that would disturbe the flow in the case i was going for...

Lol.. it is indeed mentioned quite a lot at 61'C though.. both my fx8120 and fx8350 are hotter running with OC, though both undervolted as much as possible with an OC set to near max obtained clocks at stock vcore.. the fx8120 is running almost daily for a few hours upto 24 hours for about more than 10 years.. (@4,1 ~ 3,9Ghz depending on ambient)

Lol edit: hehe you are right about recommended packagd temp.. lol got it so wrong all this time.. hehe hmmz have to adjust that, after clearing.. and lol.. besides the temp, we were saying the same thing: keep stock or go better ... 

Edit2: i still love Linux on those fx8yxx beasties.. only fx9590 went a bit overboard as it required a nuclier-reactor in the shed... wait, did that start the RBG hype?? The green glow...

[elstaci]

Don't get me started on the FX 9000 series CPUs. Those run as hot as ThreadRippers almost.

You need a powerful Liquid CPU Cooler for those CPUs. But I digress. (-:

Lol.. hehe though the fastest clocked CPU for consumers at that point in time.. though could not compete newer uarch intels.. and 225W (from the back of my mind) ... lol, i considered a used one .. until i realised 225W, and my board went 125W MAX...  you needed 990x chipset & board made out of asbestos 

Though powerusage was lower than i7 10700k .. intel fx9xxx moment.. 

[elstaci]

61c is the Maximum Operating Temperature for the FX8350. Once it reaches 61c and goes above the CPU automatically starts to throttle to keep the temperature at or below 61c.

If I remember correctly, My FX8350 would shut down the computer once it reached around 80c or slight above.

Personally the FX8350 Black Edition is a very sturdy, tough and dependable CPU. I was very happy with that processor and now so is my wife.
