Hey,

I have an E6300running at 300Mhz FSB x 7 (2.1Ghz), with an ACF7pro.

Idle temps are around 45'c, but load temps can reach 60'c!

I'm using TAT so there are core temps.

I have already tried re-seating the ACF7 but it didn't solve the problem... I have made sure that the HSF is locked down and the legs are clicked in properly. Also, the vCore voltage is at stock voltage.

I'm using Arctic Silver 5, and I followed their instructions of putting a horizontal line over the processor and just putting the heatsink on that. I'm pretty sure that the thermal paste has covered it properly. One thing, though, I've been told that I should use a rice-grain size amount - but I can't get that small amount to cover a horizonal line over the processor :confused: So it's more like 2 grains of rice..!

My ambient case temperature is 27, a couple degrees over the room temp. I have a 120mm fan sucking air out from the CPU, and a 120mm fan sucking air into the case at the front. I also have an 80mm fan blowing into the side, although that fan seems to be pretty naff.

Any suggestions? :)
 
i dont get this horizontal line thing, how can the paste spread its self out if theres no where to move, for example if i crushed you under a massive brick you wouldnt be able to move to its edges would you.......

i put a pea sized amount on the middle and spread it out evenly, and i got sub 50 degree temps at 3.2ghz on the same processor.
 
I've just reseated forgetting about the whole horizontal line thing as you suggested, and my temps are 56/57'c under full load in TAT. So ignoring the horizontal line thing has knocked about 3.5'c off, but still it isn't cool enough for my liking..!

I'm thinking of turning my 120mm fan around so that it blows air into the case, and onto the CPU cooler, rather than sucking it away. There's grills on the side of the case... but maybe it will be better to have more cold air blowing in than trying to suck the hot air out? What do you think?

Do you think that I should try putting my ACF7 at a 90' angle if the above doesn't do much? Like, incase it's not sitting properly? I don't really want to keep it blowing at that angle though... Because then it will either be blowing air into the GFX or into the PSU! :(
 
Hmm, I still have the same problem..! 65'c on full load at 2.1ghz! :eek:

Now I have 3 fans blowing air into the case, so there's more cold air going in there than you can shake a stick at.

The ACF7 is pointing upwards towards the PSU, there is a 80mm fan blowing downwards onto it from the side panel, and 120mm blowing onto it from the back, and a 120mm drawing air into the front of the case. If you put your hand over the grill on the side panel, you can feel reasonably cool air coming out of it.

Ambient case temp is 27'c.

I've tried pushing down on the ACF7, to make sure it's seated properly, but it doesn't change the temperatures at all so it must be making best contact as possible already..?

I'm running out of ideas..! One thing I'm thinking, is that the IHS isn't contacting the cores properly..?

:confused: I'm stuck! What do you guys rekon?

I have a temperature probe on the bottom of the heatsink, and it's displaying 38.4'c on idle, but the core is displaying 52'c on idle... That's a big difference, right? It shouldn't be that big? :confused:
 
You could have a faulty board, or just a bad chip :(. Im running a 3.3Ghz OC well experimenting with a bit of a voltage increase and my idle temps are 36 - 37.
 
i take it your using stock volts for 2.1ghz?

If youve reseated the cooler numerous times with very little change in temps then the cpus IHS may not be flat. Convex conroes seems to be a relatively common problems. I had this issue with my e6400 and needed to lap the IHS to get better temps
 
:(

Do you know what your "FPO#" is? Mines L629B275, so I think my week/stepping is 29B ..?

I can touch my ACF7 and happily keep my fingers on it till I get bored - should it be hotter than that? I've tried touching it right at the bottom on the copper base, too. If the core is 51'c, surely the heatsink should be pretty hot too..? The heatsink doesn't even feel as hot as a car that's been in the sun...

Oh right, what were the before/after temps?

Can you tell me how you did it?

Yeah I'm on stock volts (1.25 or 1.22, not even the 1.35v spec'd!)

Also, an uneven surface could explain the difference between the two core temperatures (I've only been giving out the highest temp - the temps are atm, idle, 51 and 47).

Wahey, three posts in a row :p

Regarding lapping the CPU..:

I have held up the CPU and Freezer 7 Pro to a bright light, and it looks like it's only the corners that are touching the freakin' heatsink!!! I can see the light through the center. See my paint skills below, the yellow bit represents the tiny gap I can see:

So... lapping? Should I do it and just hope i never need to use my C2D's warranty?
 
yes lap it.

Also TAT is t eh suck. Who cares about temps that much if you can get it stable. I saw 70C in speedfan with my C2D, wonder what TAT would think to that :p

I lapped my C2D, cpu's never break anyway, only if you are asking for it. Mine is running 3.5ghz with about 1.45v or something. Load is about 60C in speedfan.
 
Some mobo sensors with certain BIOS report the wrong temps. You don't mention what board you have so it's hard to tell if this is the situation in your case.
For instance on an Asus PW564WSPro there are a number of BIOS revisions that report an incorrect temperature no matter what software you use to monitor the temperatures. It may be worth researching your mobo and BIOS to see if this is the case.
Does your mobo automatically adjust the rpm of your hsf according to temperatures? Are there settings in your BIOS for 'quiet', 'performance' etc? Are you also monitoring fan rpm alongside temps?
Going from 40c idle to 60c load is nothing unusual...both are a bit hot for your cpu running at that speed though.

Yeah your temps are too high, I'm getting 35 idle, 55 in orthos with the 6300 at 3.4Ghz. Cooler is a Tuniq tower with AS5. If I were you I would spread a very thin layer of AS5 over the chip using a credit card, get it as thin as you can without leaving any areas bare. Thats what I do anyway and it seems to work a treat!

Are those temps using Intel TAT?

Would probably think you're an idiot.

70c in Speed Fan (if incorrect and probably is) has to be at least 85+ in TAT, that's just stupid. :rolleyes:

:rolleyes: What a *****.

How do you know what a cpu can take? Have you ever heated it until it stopped working?? Didnt think so... :rolleyes:
 
yeah, using Intel TAT. This very second its telling me (CPU 0) 36 - 3400, (CPU 1) 34 - 3400

Its at idle as I'm only on the net.
