Can someone please suggest me a cheap heat sink that'll keep my pc quiet. I don't use pc for gaming but after I run couple programs at once it'll start making loud noise. It gets very loud when I run Nox (Androiod Simulator). Everything is stock in the PC. I am not sure if I measured correctly but the dimensions i got for the fan were 3.25 in which converts to 82.55 mm?

You didn't state what case and what case fans...so going to pretend your system has decent airflow. And suggest the best little cooler for $19.99 is the Cryorig M9a

Or you could just replace the fan. Assuming it's the stock (old style) AMD A8 cooler. Does the cooler/fan look like this:

If yes, then you could replace with the Arctic F8 for $6.99 or Noctua NF-R8 for $9.99

Replacing the cooler and not just the fan will result in cooler temps and less noise.

The case is m11bb I believe which is very small and yea the heatsink does look like the pic. Here is the link http://www.asusparts.eu/Asus-13071-00220400
I just have a quick question the m9a you suggested is 92mm and if I measured correctly my fan was 80mm...will 92mm work just fine? I just want to keep the noise down as much and I am willing to spend more than 20$...

The m9a is a replacement for the cooler and the fan. The 92mm fan on the m9 will be much quieter than the stock 80mm. However, it's a bit more work to replace the entire cooler than just the fan. But, worth it, imo.

Also the Asus m11bb doesn't appear to use any intake or exhaust fans. Might consider adding case fans as well - if the Asus design allows it.

by more work you mean i just need to take old one off the cpu carefully and clean it up and apply new thermal paste and fit the new one on?Here is the picture of the back: http://imgur.com/a/RFLXw
I can possibly add another fan in the back? Also do you have any better choice than the m9a anything better or this is good enough?

So the following is what I need?
1. https://www.amazon.com/Cryorig-Mini-Tower-Heatsink-Cooler/dp/B0177GTUE6/ref=sr_1_9?ie=UTF8&qid=1473142164&sr=8-9&keywords=cryorig
2. https://www.amazon.com/dp/B00PPNV9OI/ref=olp_product_details?_encoding=UTF8&me=
3. an additional fan in the back for sucking hot air right not blowing? any fan suggestions on that?

thanks

Yes, that list is good to go.

Can always spend more and get more performance. The Cryorig H7 would be a good step up. Need to measure the space in the case available for a taller, larger cooler (H7 is 147mm tall). If there's enough clearance for a 160mm cooler, the Reveen Justice would very good as well. From there it's diminishing returns for a non-OC'd apu.

Does the case exhaust mount support a 120mm fan or 92mm?

If 120mm, the Arctic F12 is a great low cost case fan that integrates a PWM splitter, so the F12 and the CPU fan can share the same header and the F12 will match the thermal profile of the cpu fan.

If the case only supports a 92mm exhaust fan then the AC F9 is a good choice - it features the PWM splitter option too.

The case allows 92mm and I ordered the AC F9. I didn't get the that fan yet but I got the heatsink and I installed it correctly today. However HWMonitor is still displaying high cpu temps and I don't know if those are normal or not. I tested five different apps and they all showed different temps. Can you suggest me a good accurate cpu temp app? Also I only used HWMonitor before install new heatsink and before it showed 1849 rpm with cpu temp 80 degree Celsius when I started the computer and after three hours it was 3879 rpm with cpu temp 98 degree Celsius and now after running it for one hour with new heatsink it reads 1418 rpm with cpu temp of 95 degree Celsius. Do you think HWMonitor is inaccurate?BTW My pc is really quite now, it doesn't sound like a flying yet no more :)

Congrats on grounding the jet fleet. The peace and quiet might help you resolve the remaining sensor issues.

Some of those monitor values are...crazy. I recommend HWInfo too. HWMonitor is very good as well. However, the sensor values reported are only as reliable (inaccurate?) as the motherboard says they are. What are the temp values in the BIOS? Do you have the latest BIOS installed? Does the BIOS allow any sort of vcore adjustment?

And those reported high temps could indicate poor case airflow. Will be interesting to see what happens when you install the F9.

I think i do have latest bios because i remember flashing couple weeks ago. i tried couple monitoring software and even checked in bios but my case fan isn't being recognized by any of them but it is spinning. I did plug directly into the motherboard using a 4-pin. i have the pic below can you please check if i installed it correctly....I also attached bios screenshot. the first day I installed heatsink hwmonitor was giving 1500+rpm and over 90 degree temp but now for the past few days its been between 60-80 with less than 650 rpm(hwmonitor) with normal use. i think the first day temp was inaccurate because of installing new heatsink? bios is reporting under 50 temps.

The exhaust fan is installed in the intake position. ;-)

Which may or may not be what you wanted. The flow secret to fans is that the blade side is intake, the struts and motor side is the exhaust side. Usually want the air flow from the case fans and cooler fan to flow in the same direction. In this config, the fan's air flow is 'pushing' into each other.

The red arrows show it in the exhaust position and the blue arrows show the fan mounted in the intake position (like yours)


You might try flipping the AC F9 orientation to the exhaust position to see if the temps improve even more. In the current config the fan is pushing cool air to the exhaust side of the cooler...not ideal.

Can't see from the photo, but do you have the F9 plugged into the cpu fan header and the cpu cooler fan plugged into the F9's pwm female connector?

The CPU fan is plugged using four pin or three pins on the mb which says CPU fan and case fan is plugged in using four pin pwm plug on mb where it says case fan.

That's an acceptable connection arrangement.

The F9 with its daisy-chained pwm connector allows the cpu fan header to control both the cpu cooler fan and the F9. Doesn't mean you must use it, but can be a useful option as the F9 (in exhaust mounting) will spin up as the cooler fan spins faster - but should run quieter at idle - so that's always nice. It's worth trying out that config to determine which is better with your system.

The F9 PWM cable would connect to the cpu fan header. The cpu cooler fan connects to the F9 female pwm connector. The single wire cable from the F9 can be connected to another fan header to report the rpm of the cpu fan, as the rpm of only a single fan can be reported by a single header. It sounds more complicated than it is.

i did connect it that way now but i can't really figure out which one is the actual cpu temp on hwinfo is it the one that that says cpu 0 or cpu 0 package or its under asus m11bb which says cpu and motherboard? the rpm didn't change much after installing the case fan...

The CPU 0 and CPU 0 package are the temps - 1st one is a tad optimistic and second one a little pessimistic. What do the temps read in the BIOS? Could use the temps in the BIOS to calibrate the temps in HWinfo. (Right-Click on the sensor name in HWinfo to change the offset)

Did you connect the single fan lead from the F9 to another fan header? Only see the cpu fan header rpm in the screenshot.

i connected the cpu fan to the f9 using the male to female connection or what ever that is called lol...and f9 where I had cpu fan plugged in earlier. both fans power on but for some reason when i had attached both on diff places on mb it wasn't being detected but it was spinning and same now its spinning but not showing up anywhere as case fan. bios temp been around 55.

Connection sounds correct - cpu cooler fan connected to F9 and F9 connected to cpu fan header.

There should be another single wire with a 3pin connected from the F9 that can be connected to any 3pin header on the mb.

Temps seem much better and that's the important part.

bingo!!!Now the fan is being detected by bios and monitoring softwares...I thought the the additional three pin was extra but i didn't know i had to connect that also lol...on my mb it was 4 pin the wire was 3pin it is still okay right?
also on your previous post you said something about calibrating and when i right click I don't see that option...can you please recheck the instructions on that?there is configure sensor at bottom but couldn't find the change offset option.
avg is down by like 10 degrees. http://imgur.com/a/pJTg7

Yes, 3pin or 4pin header is fine - it's just one pin only required - the rpm report pin.

Sorry, right click is to adjust tjmax. Have to dive into the options - select custom, then select each core temp sensor and in the bottom left under 'customize values' change the default multiplier to 0.xx to get the values seen in the bios. Or enter a negative value offset in the add box.
