i bought a FX 8350 processor and installed on a Gigabyte Mother board with the fan it came with the processor. it is making loud noise.
Could someone help me to find options for reducing this noise. sometimes the noise is unbearable. The system working fine with no issues.
An aftermarket cooler is your best bet. Aside from the new Wraith cooler packed with the 8370 and some other models, AMDs stock HSF makes a 737 seem quiet. Liquid cooling is dead silent, even under full load and elevated ambient temperatures.
The larger aftermarket HSFs run the fan at lower speeds and still move plenty of air to cool your CPU. The small OEM fans must spin at high speeds to cool power hungry FX CPUs. The link below has a wide range of HSFs in all price ranges along with installation and performance reviews to help you find an aftermarket HSF that should work well and be much quieter than the OEM fan. You should also make sure that your mobo model supports the FX-8350 CPU as not all mobos have the proper VRM design to handle an 8-core FX processor without problems.
FYI - Liquid coolers are not "dead silent" as the fans required on liquid coolers must produce higher air pressure than fans on HSFs to force air thru the radiators, thus liquid coolers can and often are louder than those used on quality HSFs. Reputable websites show fan loudness in addition to cooling performance. The link below illustrates the point with the Corsair H100 having a 59.2 dBA maximum noise level while the Xigmatek Aegir SD124268 is only 49.1 dBA. It's worth noting that 10 dBA is a major increase in noise compared to the Aegir HSF. In addition to the coolant leak liability of all liquid coolers, many people end up spending more money changing fans on liquid coolers because the OEM fans are so noisy. HSFs do not introduce the cooler leak liability of liquid coolers even though top quality tower style HSFs perform as well or better than many liquid coolers.
While maximum Fan speed is rather loud on a lot of H₂O AIO's... For normal everyday use the fans will be on "Quiet" and barely audible. My H80i is superb at keeping things cool and quiet.
From your site:
Here is how things actually stand up when talking about fan noise:
I highlighted only the ones that were both <40dbA AND <20°C
Almost all H₂O AIO's cool very well and keep things very quiet. Your favorite site does a very poor job of keeping results in this chart. As an example here is the results for the latest H₂O cooler they tested on Jan 04, 2016:
Manufacturer: Model No.: *Fan Speed: 125W Thermal Test (°C) Noise Level (dBA)
DeepCool Maelstrom 240 low 11.9 34.3
yet it does not include my H80i or other coolers.
Also here is a nice quote taken from the above test:
One nice aspect to liquid-to-air heat exchangers is that their narrowness tends to respond favorably to lower air flow situations than say a tower heatsink, consequently with both fans slowed all the way down, the Maelstrom 240 only sees test temperatures increase to 11.9°C over ambient.
So to sum things up. H₂O All-in-One coolers do an excellent job of cooling while also keeping things very quiet. And while yes, there is the extremely rare occurrence of a coolant leak, you have a better chance of being hit by lightning or winning the lottery than this actually happening.
Not to mention the people who use aftermarket fans. With my Corsair H105, the stock fans were -horridly- loud, but a couple of Cougar CF-V12HP fans, which I had already been using as case fans, spinning at around 1000RPM, it's inaudible. And as you pointed out, a lower fan speed isn't nearly as detrimental on cooling efficiency with liquid as air. In the case with the H80i, or any radiator, two fans spinning slowly in push-pull create a massive amount of static pressure. Airflow may only be 30cfm, but airflow is measured in an open environment, and what matters most is eliminating "dead air" space between the fins.
And then there's the fact that liquid is a much more efficient heat transfer mechanism, and the fact that Corsair offers a $10,000 connected equipment warranty in the case of a coolant leak due to a faulty unit. Heck, even heatpipes can leak, and if they do you will never smell a more foul odor in your life... Think of a mix of skunk and methane.
The fact that ALL liquid coolers introduce a very real and serious leak liability not possible with a HSF, is reason for all knowledgeable PC enthusiasts to take pause. The fact is CPU heat = fan operation which is indisputable. A liquid cooler needs to run the fans just as a HSF does to cool a CPU under medium to heavy loads. In addition HSFs are far superior in efficiency to AIO/CLC liquid coolers. The top tower style HSFs even cool better than the Corsair H100 and lower model AIO/CLCs many of which can not cool the 8-core FX-8000 and 9000 series CPUs properly. The cost of liquid AIO/CLC coolers equal in performance to a quality tower HSF often cost 50% or more than a HSF.
Many people are confused about processor liquid coolers and assume that water cooling must be superior to HSFs when they are not. Unlike in an automotive application where the coolant flows thru the heat source (the engine), with processor coolers, the water only flows over a water block mounted to the top of the processor. The water transports the heated water to the radiators which require high fan speed/air pressure to cool the water flowing thru the radiator. The cooling medium in a liquid processor cooler is AIR, not water. In contrast a HSF removes the processor heat via a copper/aluminum block and/or with direct contact heat pipes. Heat pipes use phase change cooling which is more efficient than the liquid cooler approach. HSFs are used on 99+% of all consumer CPUs/APUs for obvious reason. HSFs are bullet proof reliable, they are highly efficient and they are quiet unless you choose a loud fan option. Larger tower style HSFs are even used without any fan for people who desire a totally silent PC experience.
In my experience when people understand the technical pros and cons of HSFs and liquid coolers, they are usually able to decide what works best for their application. Without knowing about the coolant leak liability in liquid coolers many people have suffered serious PC hardware damage, loss of data and loss of use of their PC. Since there is no AMD consumer processor that requires a liquid cooler to maintain proper temps there is no need to introduce a water leak liability in any PC and that's a good thing.
The main problem is that you cherry pick your stats, you claim that AIO H₂O coolers leak on a regular basis and in general present a fear mongering approach to recommendations. The site you use to cherry pick stats even shows that ALL of the top coolers are liquid all-in-ones. And if you bothered to research any of the top tower HSF coolers, you'll find that they are almost as costly as a decent H₂O AIO. If you take cost, noise and cooling into account there is nothing better than an H₂O AIO. I will continue to poke holes in your scare mongering. Leaks can happen (usually user error/tampering) but it is so rare. If it was an issue like you suggest, NONE of these companies would be in business.
Only leak I have ever suffered was from my own doing. Only damage was to the BIOS clock, then ASUS replaced the mobo.
Other than myself not paying attention during installation and testing did I get a leak, never had a hose come off a fitting or the like. Water cooling is the best cooling you can apply to a PC component, removing the heat immediately at the block and transferring that immediately when the water leaves the block. There is no argument to the efficiency of watercooling or its safe use around expensive components, on overclockable AMD CPUs its ideal. Simple as that.
