Trying to keep my e8400 cool!

post #1 of 12
Thread Starter 
Hey guys so I'm working on a stable OC with my sig rig...Sorry I'm at work so I don't have access to the exact numbers but:

I have the e8400 up to 4.0 with around 1.25v and it is rock solid, am able to run Orthos for hours on end with no errors. Of course, I had to unlink my RAM to 2:1 ratio so it is running at about 866.

Overall I'm extremely happy with this OC, it seems stable and I can really feel the difference when benchmarking with AoC and CoD4. Also was able to pull a 14087 3dmark06 (up from 12300 or so at stock speeds). The only issue I have here is the HEAT!

Now I realize that the staggering temperatures outside might effect it somewhat, and also that after awhile I should see a few degrees lower once my thermal paste really kicks in. Unfortunately, I have reseated 3 times now and the temps are still a bit outrageous...

Idle this puppy sits at around 40-45C, then after being on load for a few hours I'm looking at around 70C! Is this even safe for an e8400? I'm using a Zalman 9700 heatsink, and I used AS5 when seating. I followed the AS5 instructions for dual core processors to the tee using the pencil tip trick I found in another thread on these forums.

Does anyone know what I can do about these temperatures (short of moving to water cooling or buying new parts)? Do I just need to continue reseating until I get better results, or could this maybe be the result of a faulty HSF or CPU? Or am I just stupid?


Thanks in advance for the help guys!

What temp monitoring programs are you using? RealTemp monitors the 45nm processor's temp right as it is set with a 95c TJmax. Coretemp and the like using a wrong 105c TJmax for the 45nm thus resulting in a temp of 10 degress higher.

So if you get 70c on coretemp, your actually temps are 60c.
Acceptable, but you can probably do better.
Just try reseating the HSF. Also the Zalman 9700 benefits from having air flow in the direction of the heat sink.

Unfortunately yes I am using RealTemp.

And I have my case wide open with a big room fan blowing straight at the heatsink...

Would it be possible that the big fan is causing turbulence?

Something doesn't make sense, what are your ambient temps for the room it is in.

That's a pretty high load temp on that, is the cpu fan at 100%?

My friends temps are about the same... I'd recommend trying to reseat also...

As a side question: What are the acceptable temps on the e8400 for everyday use. If I try to bump my vcore up to 1.31 my temps hit 57 (unless I sit it close to the ac vent on the floor then it goes to 54-55 but then my fan on the bottom is sucking in air that is 55F when the room is 75F so that would probally lead to condensation.)

EDIT:
What I done to finally get my temps down a little more

http://www.overclock.net/air-cooling...ver-5-mod.html

I reseated my TRUE over 10 times. Finally I done this method and temps improved but still not good enough so I took it off and inspected where the AS5 got spread too. Seemed To much of it spread to one side, so one side had a lot the other didn't have any past a certain point. So I reduced the line just a little.. and put a very small dot kinda in the middle of the area that didn't get any as5.

CPU fan is at 100% at all times. Ambient temps I don't know because I'm not at home right now, but they are nothing special trust me. I have also set this computer up at someone else's house and found temps to be the same.

And to answer other questions...

I'm sorry but the case name eludes me as well at this moment, will have to check when I get off work. As far as the room fan causing bad airflow, no I don't think that is the case because I have the HSF, case fans, and room fan all blowing in a nice little circular system out the back of the case where I've taken off the dividers for even better airflow.

I have tried all of the possible suspects at this point. Bad airflow, messy wiring, reseating the HSF. Is there really no other solution? I guess it's possible that I'm not doing a good job putting my HSF in there but I swear I followed the directions perfectly...
