Earlier today I took off my stock heat sink for AMD FX-6300, and installed my new heat sink (Arctic Air Freezer Pro 7 Rev.2) and I found the idle temperatures were good and it wasn't that loud (34-46 degrees celcius) but then I when I started playing Far Cry 3 for about half an hour I closed the game to see the CPU temperature and I had a warning message saying CPU temperature was at 65 degrees celcius! I then checked my motherboard program and it said my CPU was at 68 degrees, that is not good for this CPU right?

For that CPU those temps are in line. Nothing to worry about.

What are your ambient (room) temps? Just curious.

the FX series CPU's start to throttle the performance back after you hit around 60c degrees. So yes it is to hot. There are a couple of things to watch for.
1. did you put the correct amount of thermal paste on?
2. Did you install the cooler correctly?
3. Is your voltage set to High?
4. It takes a short time for the Thermal paste to settle after being applied.

I would Run Intel Burn Test to help heat up the CPU and set the thermal paste and see what the high temps Hit. If the temps are still to high after 3-5 days, I would make sure you are not over volting the CPU causing extra unneeded heat. If voltage is low then I would look into reseating the Cooler with fresh thermal paste.

some of the FX-6300's can run around 1.32v easily so make sure your not overvolting the CPU. this is a common issue when people build there own PC's and don't know how to stress test and find the lowest stable voltage.

I had a layer of thermal paste on the heatsink when I bought it. I think it's installed correctly, it is cooling pretty good in idle or at least better than my stock cooler. My voltage may be set to high, do I check and configure that in the BIOS?

Your lucky. It is hard for me to keep a 28 C ambient where I live (Phoenix Arizona) when it gets up to 115 F outside. Its nice right now at 72 F or 22 C. The winter is the best time of the year. :D

also if you are looking at the motherboard program it is most likely giving you the cpu socket temp which is usually good to 72 to see actual cpu core temps or (package) download hardware monitor

yes the core voltage will be found in the BIOS for the motherboard. It is very rare the the motherboard will set the proper voltage on its own. (auto) Idle temps do not mean much as the voltage and or the frequency get cut when there is very little load on the CPU. it is your max temps that matter. you should not come close to your max temp when gaming as there is not enough constant load to make it hit the max. If you are hitting max temp when at stock frequency's then your voltage is way to high.

Use CPU-Z to know the actual voltage with the system running as there usually is a difference between what you set it for and what the voltage really is. www.CPUID.com If you do need to turn it down use Prime95 for a minimum of 5 hours strait and Intel Burn Test set to maximum memory and for 40 runs to be sure you are stable. If either one fails your CPU is unstable.

I got CPUID HWMonitor and I see under Voltages my CPU VCORE max value is 1.320V,that not too high is it? Also it seems that the temperature of the CPU socket and actual CPU are much different! The higher numbers I been getting must have been from the socket, but the actual CPU is much cooler than I expected. Right now the socket says 37C degrees and the actual CPU is 18C degrees. So I think my temperatures have been fine all along right?

If that is the max when you put the system under a load by either playing a game or stress test then your fine and no need to drop the voltage unless you want to achieve lower temps.

Sorry that was just in idle lol, i'll check some games first. So would 60C degrees be the highest safe temperature on the CPU? If that so i'll open up Far Cry 3 and play for a bit and right after I close the game i'll check the temperature of the CPU

the FX series CPU's will start to throttle the frequency (drop the frequency) anywhere between 60 - 65C so the Max you should hit would be around 60C to get the max performance form the CPU. The CPU will not be "hurt" till you hit around 72C. They built in the throttling to help keep the CPU's from over heating. When the CPU throttles the performance drops and you are left with a weaker CPU than expected. This can cause issues in games and stuttering.

some other things that help keep the CPU cooler are wire management. Keep the wires tucked neatly to the motherboard mounting plate. Clean the fan blades, and filters if any, in the case. Set the CPU fan to hit full speed at or around 45C. these things are free and help control the CPU temp.

I got my wires tucked in so that should be good, but I will make sure to check for grime on the fan blades! I also forgot to mention that I can install two 120mm case fans in my case. And one of them being right next to the CPU! I forgot about that completely! Getting those case fans will also improve my temperatures right?

depends on where they are. As an example of it being a temp hindrance, My gaming case is a Antec 900 II with a 120mm side fan to help cool the GPU and the CPU. with it blowing in like it was designed for, it pushes to much air onto my GPU making it heat up more than with out it being there. So I turned it around and have it sucking the heat from the GPU out. This is just an example of how it can hinder you in cooling. For you you may not experience this and it may help cool your system better. You also need to try to balance the intake and exhaust fans so that you end up with just a slight positive pressure to prevent dust build up on components. To much positive pressure can hinder cooling but you will have a lot less dust build up in the system. If you have some fans kicking around (or a friend that does) put them in for a test and see if it helps in both GPU and CPU temps. You can always buy fans if you find out they help in your case.

Yeah i'll try and get a fan from a friend, but I would like to see some temperature drops so I always thought more the merrier but you had a good point about keeping it balanced, i'll test two fans and see how they go.

Look for high CFM fans (80 CFM or higher) when you are replacing fans. Sleeve bearings, or rifle bearings (sleeve with an internal groove for lube) are quieter than ball bearing fans.

Generally try and keep the Intakes (Front, Side, & Bottom if any) and the Exhausts (Rear and Top) within 15% of each other. It does not matter whether you end up with a positive pressure (Intakes greater than Exhausts) or a negative pressure because the case has screens and not fine particles filters. All air contains dust. A positive pressure is attained by forcing more air containing dust than is exhausted. The only way to minimize (not eliminate) dust is to have a micro-particles filter along with electrostatic filters and this is not practical in a computer case. (Clean room technology).

With the computer OFF on a monthly basis remove the side panel and blow out the dist by using a can of compressed air. When you do this remember to block the fans from spinning by restraining it manually. This will prevent them from spinning over the designed RPM from the compressed air blast and ruining the bearings.

This part of your statement is flawed because a negative pressure will draw air from any crack and crevasses that it can. Because of this not all air gets pushed through the screens so a lot more dust enters the system than a positive pressure system. The rest of your statement I agree with. The reason I disagree with this part as I have proven it to many people and done the tests myself in controlled environments.

For cooling, the negative pressure systems cool better but in the end it costs more in time and materials to clean the system out.

What you say will work only in a clean room - http://www.cleanairtechnology.com/cleanroom-classificat...

It makes no difference in a home environment. I will explain my statement.

For a positive pressure, the intake air must exceed the exhaust air. From where is all this extra air coming from? From around the room.

I re-iterate that it does not matter whether the case has a positive pressure or a negative pressure. I recommend within 15% of each other.

yes the air is coming from a dirty room but is being pushed through a screen to help filter the air. All I can assume is you are under a false impression that I am saying that no dust will enter the system which is far from what I have said. No matter what you do unless your in a clean room you will have dust enter the system BUT a lot less with the air being pushed threw screens/filters than being sucked through unfiltered cracks and crevasses, This Has been proven even in my home environment that is not a clean room in a case that moves close to 200 CFM. I never said there would be no dust just Less Dust.

Do not assume that a "screen" will "filter" anything. A screen is not a filter! If you have achieved good results with positive pressure, continue doing it. To me a positive pressure or a negative pressure in a home environment makes no difference.

If it doesn't "filter anything" then why do they get plugged and need to be cleaned?

edit: the screen filters are not meant to purify the air just reduce the dust intake and they work as you know because your case has them too.

The screens get clogged with dust because of the electro-static effect. Larger particles like lint from clothes adhere together (again electro-static) and build up. This is why screens should be cleaned (filters are generally discarded).

Yes my case (HAF-X) has screens and the dust has to be blown away on a weekly basis.

This is my last post as this has gotten way off subject But:

by your own admission the screens block large particles in the air from passing through it. (like lint from cloths which is cloth fibers) Here is the definition of Dust:
Dust consists of particles in the atmosphere that come from various sources such as soil, dust lifted by weather (an aeolian process), volcanic eruptions, and pollution. Dust in homes, offices, and other human environments contains small amounts of plant pollen, human and animal hairs, textile fibers, paper fibers, minerals from outdoor soil, human skin cells, burnt meteorite particles, and many other materials which may be found in the local environment.

Here is the definition of Filter:
noun
1.a porous device for removing impurities or solid particles from a liquid or gas passed through it.
"an oil filter"
synonyms: strainer, sifter; More short for filter tip.
"a cheap filter cigarette"
a screen, plate, or layer of a substance that absorbs light or other radiation or selectively absorbs some of its components.
"filters can be used in photography to reduce haze"
a device for suppressing electrical or sound waves of frequencies not required.
COMPUTING
a piece of software that processes text, for example to remove unwanted spaces or to format it for use in another application.
BRIT.
an arrangement whereby vehicles may turn left (or right) while other traffic waiting to go straight ahead or turn right (or left) is stopped by a red light.
"a filter lane"
verb
verb: filter; 3rd person present: filters; gerund or present participle: filtering; past tense: filtered; past participle: filtered
1.
pass (a liquid, gas, light, or sound) through a device to remove unwanted material.
"the patient is hooked up to a dialysis machine twice a week to filter out the cholesterol in the blood"
synonyms: sieve, strain, sift, filtrate, clarify, purify, refine, treat More
move slowly or in small quantities or numbers through something or in a specified direction.
"people filtered out of the concert during the last set"
synonyms: seep, percolate, leak, trickle, ooze More
(of information) gradually become known.
"the news began to filter in from the hospital"
2.
COMPUTING
process or treat with a filter.

So no matter how you cut it the screen filters they add in front of fans are for removing impurities or solid particles from a gas (AIR) that is passed through it. So by definition a screen is a filter that blocks large particles from passing through it. Dust consists of many things including clothing fibers that you mentioned and you also said, and i quote you "Do not assume that a "screen" will "filter" anything." end quote. Your correct that I do not assume it is filtering as I know it is filtering . Point proven!

been a good debate but wish it did not high jack the OP's thread.

Thanks! My main point is that the quality of the air inside the case and outside the case is the same. That's why a positive pressure or a negative pressure makes no difference.

I kinda agree with this. So the idea behind positive pressure is that it push the air out through the passive vents in your case instead of sucking it in. The problem with this is if your fans are not filtered then their is no point because you fans are going to suck the dust and hair in just like the vents would. And, no positive pressure does not increase your systems ability to get rid of heat. If all (and I mean all)of your intakes are filtered then it is a different story.

"And, no positive pressure does not increase your systems ability to get rid of heat."

And I actually said in one of my posts that a negative pressure actually cools better to be exact I said "To much positive pressure can hinder cooling...", there JimF_35

all of my intakes are filtered (Antec 902 gaming case) and so is my secondary PC (Cooler Master 690 II with a SilverStone 140mm x 280mm magnetic filter for side cover). A Long time it took me to test all the variables to what worked better and was more efficient vs effective. I always recommend filtered fans or buying filters for all intake fans. At around $5-$20 USD the filters are well worth the extra spent VS. cost of compressed air and lint free wipes.

If you push air through a filter into a box will the air quality improve in the box? Yes it will, now it will not be clean room quality but there is a measurable difference in the quality of the air. This is exactly what happens with the screen filters installed on PC's. In a positive pressure system that the air is forced through screens the air quality is better in the case then out side the case. OK let me put it another way IF you leave your home windows open and the screens up for the hole summer and your neighbor leaves the windows open in their home all summer but screens down which one will have better air quality and less unwanted items in the home? The one that left the screen down will. We are not talking clean room clean here, we are talking house hold air filtered with a small screen. IF the screens did not filter out impurity's then they (the screens) would be clean. Now if it is filtering out any impurity at all then there is a difference in air quality on the other side of the filter.
