Hi all.
Finally got my comp together on the weekend, but have some issues with tempratures.

Idle it's sitting at about 44 (which is the ambient temp also). As soon as it goes under heavy load, ie gaming or desktop activity it can reach 62/63.

I am thinking that the Coolermaster Sileo 500 may be the cause as the temps drop 3/4 with the side off. Nethertheless those temps seem very high. I am on Windows 7 64 Bit which might add a few degrees form reading up. I am using a Titan Fenrir on full rpm (which I might add is loud as heck).

Can anyone let me know safe operating tempratures for that CPU. At the moment I have zero room to overclock, which means the case, cpu or whole lot goes back :rolleyes:

EDIT: Looking at the Corsair H50-1 at the moment ;)

how many case fans do you have? The removing the side panel thing means you might be making an oven.

EDIT: its got two 120mm fans so should be ok. With a fenrir you should be good; as the previous post look at the mounting.

Thanks for the replies.

I reseated the HSF yesterday (third time), got a little better temps with one panel on the case open:

Idle 37/39
Load 55/59 (prime95 after 10 minutes)

Either way thats still poor considering thats at stock speeds with a Titan Fenrir at full whack :mad:

Probably chucking this back and the board for an i5 which seems to have no heat problems. Possibly rash, but those temps are daft.
 
it is hot.

My unlocked Phenom II quad hits 36C at load under prime @3.5. (well 46C on the mobo sensor which equates to 36C on the core temp).

Is your case getting warm? All that foam padding must insulate it a little. Have you got a heat brick GPU in there too?

No One seems to have answered this, AMD state the max temp is 62C.... so are sitting right on the edge. something is definitely up with your setup though, should mid/high 40s at stock in a reasonably cooled case.

I'm getting low 50s (peaks at ~53 after hours of gaming) at 3.8ghz on the stock cooler

Lul's, you're doing something wrong, at 3.8GHZ I max 48C using a T.R.U.E

Well that is the problem, I aint :D
I have fit many a CPU and overclocked in the past with no problems. As I say, this is the third time now for the HFS fitting, still the temps get to 59. This is with the case open, which makes it worse to think what the temps would be enclosed.

Yesterday I was practically in a bio suit with a quarantine zone around the pc while I applied the paste and reseated it. So it could be the base of the Fenrir, a dodgy CPU, or even mobo. Just not in the mood for this sort of troubleshooting hence my desire to ship the mobo/board/hsf back in place of an i5. I still have the retail fan unboxed, so will try that tonight as a last resort, if temps are the same, it's going home.
 
Ambient temp of 44? you mean ambient case temp, i guess?

How many fans have you got on your case? You may just need better airflow into and out of the case.

My oc'd 720 BE sits at about 22-25 idle, and 42 under P95 load (several hours), with a TRUE.

I definitely think its likely to be a lack of airflow in the case, especially if the temps lower when you take the side off.
 
From a cold boot it idles at 37/39. The ambient temp is from HW Monitor & AMD OD. All with an open case.

The problem with my setup at the moment is the airflow. PSU blows onto CPU which blows onto the 4890 which has nowhere to go. The two case fans on the Sileo only run at 700rpm, But thats the design of the case. Even so, if an AMD 965BE can't run in a Silent case without hitting maximum tempratures on stock settings the package seems to not work in my eyes.

I could have gone for the HAF 922 but didn't want so many open vents/noise.

I'll try the retail fan tonight and see what happens.
 
Ok so got home and installed the AMD HFS.

Idle temps were about 37/39 wit the Fan on Auto. I ran Prime95 with the results below. Case was open and ambient room temprature was mid 30s:

The HSF and fan was installed correctly using the paste that comes with it, which was as 'stock' as I could get it. To me thats way to high, given that I've removed the HSF from the equation, could this just be a dud CPU?.

Sileo 500 or HAF 922, seems irelevant if the retail fan is chucking 6000rpms worth of 35 degree heat on it and it still maxing out at 62c.

RMA time I guess :confused:

are you getting the same idle temps with your stock amd and 3rd party amd coolers?

that would say to me that the fenrir cooler is duff.

and the amd fan spinning up to 6000 makes me think that its not up to the job of a 965 @1.39V. i think its the same fan that barely cooled my 940 @1.32V

i would also say that a quiet case is never a cool case. i know the amd stock fan performs really well with even a slow spinning roof fan above it. and the h50 will want a cool air supply which is not 44C case temp
 
Idle temps vary. Originaly they were 44. After I re-sat the Fenrir they dropped slightly to 39/41 on average, this with the case open. So reseated three times, and each time I couldn't get lower idle temps than 37, which was the Stock cooler on auto, which I think was roughly 3000rpm from a cold boot.


I agree the case was not the best choice with overclocking in mind, mistake on my part. Even so, without overclocking, case side open, and mid 30c ambient temp, 62 at full load is wrong. Even a HAF 922 only blows ambient heat around, it's not creating cool air so to speak.

I was wondering if the Windows 7 64 Bit might be an issue, but thats my OS of choice now. Still I'm installing XP on a spare HD now, just to confirm it's not the OS.

To be honest a HAF 922 can't make much more noise than the Fenrir or stock :D


If it's not the HSF, or the case (ie open side), surely it's the CPU. Or can it be something else :confused:
 
There's summat amiss there, I was getting lower temps than that when I realised the fan on my Fenir wasn't plugged in. :P

I'm on 64bit 7.

What paste are you using? How are you applying it? Can you be certain you've got enough in? I had to add quite a lot for this setup, I was suprised how much it needs to splurge a little bit out all the was round.
 
mmm the haf only blows ambient heat around....

it blows air from outside -> inside the case, therefore then internal case air temp will drop = lower temperature air flowing over the heat sink = cooler cpu temp.

it might be an idea to try a strong performing case fan or two, if that helps significantly then we know its the case thats casuing ur problems.

the situation u are describing right now makes me think that using a different cpu cooler will not have much effect until u drop ur case temps.

Edit: you got somehting in there (tempin2) that is reaching 80 degs, that might not be helping ur temps.
 
What motherboard are you using? should give us an idea what the TMPIN are relating to..

As most have suggested sounds like a case airflow issue.. your heatsink is only going to keep a delta above ambient, so higher ambient = higher CPU temps no matter the cooler

Well my point was, unless you are passing colder air other than that of room temprature, all your doing is effectivley moving air out of the case, so having the case open is virtually the same. I agree that a perfect airflow will keep the temps down, but again, only to whatever it's pulling in, ie ambient/room.

So it is not airflow. Case open is as good as 'standard' cooling, ie not water cooled. I mean the HSF, 4890, PSU Fan, and two case fans are all fixed by location, so those are just the way they are, not much I can do with regards airflow other open the case.

Not sure what TMPIN is. I have two case fans and only one shows up on AMD overdrive but both are working. I even upped the rpm on one of them to 700.

Mobo is Gigabyte GA-MA770T-UD3P AMD 770.

Confuddled :s
 
ok..

as i have read for that board..

TMPIN 0 = CPU
TMPIN 1 = SB
TMPIN 2 = NB

So you are running 42c at full load which is about right..

The board is known for its high NB/SB temps.. have read a post stating that 80c was the confirmed 'normal' temp from a gigabyte source

I would download AMD Overdrive and see what it thinks your CPU temp is
 
(yes ur right about the open case i didnt understand what u meant the 1st time, sorry)

if this is your board:

gigabyte_ma770t_ud3p_layout.jpg


i didnt know the 770 was supposed to be hot, i knew the 790 was so i kinda suspected it.

looking at your board layout, u got the 80C rising straight up from the nb to the cpu. so imagine how hot that will make the cpu and the cooler!

without a strong airflow the heat from the nb heatsink will go straight up

this is gona sound really dumb, but working on the principle that heat rises maybe try the open case thing, but with the case on its side so the heat off the nb rises out of the case?
