Hi,

you don't say what kind of cooler you are using on your CPU but, if you are using the stock AMD one then my advice would be to get hold of a different one.

Another area to check is the thermal paste. Something like the Noctua NT-H1 is a really good one and sometimes just changing this an re-seating the CPU cooler can make a difference.

The AMD CPU's do tend to be a little on the toasty side, especially when you overclock and making sure you have enough direct cooling as well as a good air flow through the chassis is very important. I personally use the Noctua NH-D14 Air cooler and noticed a substantial drop in temperatures once I changed. Check this thread for more details: http://forum.giga-byte.co.uk/index.php/topic,1784.0.html

Hope this helps

Just to add to absic's advice your case fans are out of balance 5 blowing in and only 1 blowing out is not going to create a good airflow through the case. Try and balance them more evenly and get a nice steady flow of air through the case.

I tried blowing out 2 fans on the side cover. No avail. All permutations possible tried. Even tried 1 in and 5 out

Regarding thermal paste. Seems a good option.

Yes not a great case as far as the cooling goes. What about using the rear and side fans for pushing and the front and top for pulling? That should give a more balanced airflow past all the main components.

When I was using the Stock cooler I also got the kind of figures that you are reporting, (I was using the AMD Phenom ii X4 965BE C2 140W) that was why I changed it. You don't have to go to the expense of the Cooler I chose but it might be worth investing some money into a different CPU Cooler as you will really get better temps and also more headroom for further Overclocking.

That is what I was thinking ie., blow out front panel top & bottom. Will try this evening and report back.By the way I have a 6" Coolar master fan at the front bottom and a standard 3" inch at front panel top. Will reverse air flow of 6"fan from blow in to blow out.

Post by: Dark Mantis on July 26, 2010, 12:04:05 pm
I think that is at least worth a try and it's not costing you anything, although I do agree with absic that a good CPU fan and paste is important.

Even if you do have good case airflow, if you're overclocking a 3rd party heatsink/fan is a must. Like absic115 said the NH-D14 works well on AMDs

This is very true, I have excellent airflow through my NZXT Tempest Evo and I was still getting high temperatures on the CPU until I changed Heatsink.

Reversed 6" front panel bottom fan. No improvement seen. Will have to seek a good CPU coolar. Unfortunately Noctua fans are not available on this side;India. Will have to try something else like Coolar master
Title: Re: CPU runs hot
Post by: Dark Mantis on July 27, 2010, 07:53:06 am
Even if it hasn't made any difference to your CPU temps it will have improved the general airflow in your case. This will help all the components and once you change your CPU cooler it will all make a difference.

Hi there,

As I stated before, the only way you are really going to bring your CPU temps down are with a third party cooler and a good quality Thermal paste.

I have just swapped out my X6 1090T for a X4 965 (C2 Stepping) CPU and even with my Noctua cooler I have seen the temperature jump by 12°C. These X4 Phenom ii CPU's do run hotter than I would have expected and I'm not even attempting to Overclock. It is relatively cool here, at the moment as it is still early morning (outside temp about 20°C) but this X4 is showing temps of 36-38°C and it is doing hardly anything.

Title: Re: CPU runs hot
Post by: Dark Mantis on July 28, 2010, 08:54:58 am
Absic is absolutely right about you needing a better quality heatsink and fan for the CPU. You are not going to bring the tempertures down without one and some good quality thermal paste like Arctic Silver 5.

Guys,this is it. Ordered Corsair H50,comments please. I choose H50 over Noctua ND 14 is price is almost the same and my rig gets water cooled
2 questions
H50 pulls the air into the case the blowing radiator air in. Should I reverse the fan ?
Is pre-applied Thermal paste on H50 good enough ?
Also there is debate on using 2 fans ,"push pull". Will adding another fan help ?
Title: Re: CPU runs hot
Post by: absic on July 28, 2010, 11:51:58 am
Hi,

I did consider this option myself, before buying the Noctua. It does have some good reviews and from what I have read about it should bring your temps down quite a bit. I have also read that it can be a little tricky getting it to fit properly so be careful and read the instruction manual carefully prior to installing.

Good luck and let us know how you get on.

EDIT: You changed your post! To answer your questions:

I believe that it is designed to draw cooler air, from outside the case, through the radiator to promote better cooling. So I think you should leave it as it is. (But I'm sure someone will correct me if I'm wrong)
The thermal grease that is applied to this cooler is OK so you should have no worries there
Title: Re: CPU runs hot
Post by: Dark Mantis on July 28, 2010, 11:52:48 am
As far as it goes there is nothing wrong with the H50. It is easy to install and should certainly bring your CPU temperatures down. Obviously absic and I have a slight difference of opinion about the installation. I haven't ever fitted one but I watched a video of the process and it certainly seemed easy enough.

Well as everyone is messing about with posts I thought I would add my twopenneth! As far as the direction of airflow throught the radiator goes it really isn't that important the main thing is to get a total clean airflow through the  case including the fan on the radiator. The last thing you want is to have a dead spot where the air isn't moving properly. In one end, out the other!
Title: Re: CPU runs hot

Now the results.

Well those temperatures seem to be much better and more like I would expect to see as your ambient temp is over 30°C.

Title: Re: CPU runs hot
Post by: absic on August 13, 2010, 10:44:09 am
Yes, a larger case will help improve airflow and should also help a little further with temps but, you are in a hot part of the world so don't expect too much.

I am in the UK and the ambient temperature where I am is only about 20° C so my 1090T CPU is running at 24° C (I'm not overclocking), my 4850X2 GPU at 45° C and my HDD's at about 31° C. As you can see, apart from my CPU the other temps are almost the same as yours. (PC has been running for about 4 hours)
Title: Re: CPU runs hot

Yes. I need to tweak air circulation for best temparatures.

Yes, swapping the fan to blow rather than pull might improve things a little but keep an eye on your CPU temperature. Hopefully it won't increase but it might do so as you will be pushing warmer air through the radiator.
Title: Re: CPU runs hot
Post by: Dark Mantis on August 14, 2010, 09:47:57 am
Generally the H50s work better when they are blowing air out of the case although this is contrary to the installation instructions. It also helps by reducing the temeperature in the case by not blowing warm air in.
Title: Re: CPU runs hot
Post by: babdi on August 20, 2010, 12:02:09 pm
Well it is a catch 22 situation. If the ambient is coolar then H50 should suck and vice versa. I did try blowing out by reversing the fans. CPU got a degree warmer. Hence switched back to defaults. As said elsewhere avg temparature here in India hovers around 30 give or take 5 deg during season change. In winter the avg. minimum is around 15-20 deg while is summer it is 30-35 deg  >:(. Also I live near coast the humidity levels are high around 95 R/H especially during monsoon though temparatures are around 25-28 deg C.
Title: Re: CPU runs hot
Post by: absic on August 20, 2010, 12:11:52 pm
Well I guess you have found the best solution. Being in India the Ambient temps are much higher than we experience in the UK and, as a result, your PC components will run warmer than here but the figures you posted previously were perfectly acceptable.

Of course, another option would be to up roots and move to the North Pole!  ;D

Hi Babdi,

From the figures that you have posted I don't think you have too much to worry about and I don't think there is much else that you can do with the PC configuration/hardware to lower temperatures much further, especially considering the ambient temps in India.

I think you should be really pleased with the results you have obtained.
Title: Re: CPU runs hot

The point right now is our ambient is around 26-27 deg. Hence thought a 9 to 10 deg CPU idle temp  is high

To be honest I think that is about right. For example here in the UK at the moment, my ambient temp is about 18°C but my CPU is running at 25°C which as a 7°C increase over ambient, but I am using one of the largest Air Coolers on the market. When I was using the Stock Cooler my temps were about 15° - 20°C above ambient! :o Still well within the specified range of the CPU but too high for my liking, hence the change of Cooler.  ;)

I really do not think you have anything to worry about and apart from going to a refrigerated water cooling system and the extra expense and modifications that would entail, there isn't much more that you could do to bring your temps down further. One of the problems of living in a hotter country I guess.  :-\
Title: Re: CPU runs hot
Post by: Dark Mantis on August 25, 2010, 09:52:12 am
Absic is right in my opinion and you can't expect much lower temperatures without going to extreme measures. I run a liquid cooling system with an external radiator and still run at several degrees above ambient. Don't worry about it and just enjoy your computer.  ;)

I did try blowing out. It only increased the temp. See my earlier posts. Actually blowing causes hot air to pass through radiators instead of cool air and hence Corsair recommend sucking cool air.

Yes I did know Corsair recommends to have the fan in a blowing into the case as standard but I have found that as long as you have ample airflow into the case the amount of heat transferred to the radiator is negligable. Of course it is always a trade off.  ;)

Tried moving H50 to top. No good. My 1st combination seems best. However I can try replacing 80 mm AMD CPU fan at the top with a 92 MM high flow. Cant put an 120 mm. H50 radiator blocs the space.

Hi Babdi,

Don't think there will be too much difference between an 80mm fan and a 92mm one, but I'm kind of interested in finding out.
Title: Re: CPU runs hot

Actually absic if you do the math there is a considerable difference in area betweeen the two sizes, however I would agree that I wouldn't expect a huge difference in real world temperatures.

I did the maths and I still reckon not too much room for overall improvement from the slightly bigger fan. :-\

How about a nice airconditioning unit mounted on the wall just above the case ;)

Thank you absic  :) and Mantis I do have an airconditioning unit at the top on the left. As said,while A/C is on at 25 deg the CPU temp drops by 2 deg ie., to 34 deg.
Well by mounting a 92 mm high CFM fan if I get a 1 deg drop i should be happy  :D

The only other thing is like they tend to do in Australia, take the side off the case and point a big desktop fan into the internals.

Else submerge the case into frigid water  ;D

There is a customising idea of putting all the computer apart from the hard  drive in a tank full of light oil(usually cooking oil) and cooling it that way. It works alright but is a bit messy if you want to change anything or something goes wrong.  8) There are plenty of videos on the web if you google it.

I have seen them all. They use a acrylic or glass tank and use non conducting mineral oil.

Looks cool but a bit too messy for me I think.  ;D And just imagine the mess if you had a leak from that! :o

Ah but, on the upside, you can cook your fish & chips while playing your favourite games!!!  :D

Back !
Revamped MB,GC,Coolar and PSU. See the signature. OC 3600, BIOS FGa (Beta),idle is 32 deg c , ambient 26 deg.  :-X
Using H70 as exhaust. 4 fans blow in. 1 blow out.Positive pressure !

Hi Babdi,

considering where you are in the world I don't think you will be able to get much better temps than those.  And you've even managed a bit of overclocking too. Well done!  :D

Thanks absic !. Now I am to start tweaking to take OC to 4.2 ghz.
This is how I am planning to do.
1) Downclock memory to 1333 Mhz. If this fails downclock to 1066 Mhz.
2) increase HTT so that I increase CPU and memory together.

Am I on the right track ?

Yes you're heading in the right direction. I don't think you will need to pull your RAM back to 1066MHz to get to 4.2 but it's nice to see that you are prepared to go that way if needed.

Good luck and keep us posted!  ;)

Ahh! there is Mantis lurking behind fall foliage. Hi there .
Yesterday I had said I will try to reach 4.2 with 1333 Mhz. I got a bit confused when I got about doing it.

Now please tell me
1) If I should start from  3200 or 3600 CPU clock keeping everything on Auto at 1333 Mhz RAM
2) Whilst the older board (GA-MA490XT-UD4P) HTT was calibrated as 200,201.... the newer MB GA-890GPA-UD3H has numbers as x1 x2.
Now this is where I get confused. Can someone throw light

Should I go on increasing HTT till it refuses to boot
Then I should start incresing NB Voltage
Then CPU voltage
