How do you lower cpu temps after OCing

[bizzyd1441]

I just overclocked my E6300 to 2.0 ghz by setting the bus speed to 333 and the fsb:dram ratio to 1:1. I left the cpu voltage on auto and it was set to 1.37. But now my idle cpu temps have gone from about 49-50 C to 69-70 C. I set the frequency multiplier from 7 to 6, but the temps remain the same.

These temps seem too high to be stable. And the extra heat seems to have increased my video card temp by a few degrees, which is a concern as well. What can I do to lower my cpu temps?

Lower speed and/or lower voltage means less heat. Easiest thing to do is to lower the voltage manually. At some point you will start losing stability, so the optimal voltage is a bit over that. To measure stability you want to stress the processor.. and preferably check for errors. Of course if I were you I wouldn't stress 10 hours for each voltage step.. but instead try to find some instability point first and after that raise the voltage and do a "good enough" stress test. Like, set vcore to 1.35 at start, then try booting to OS and run some typical stress test for a short period of time like 1-5min.. then repeat with lower voltage etc, unless errors catched.

The other route is to transfer the increased heat away more efficiently.. but that relates to TIM/heatsink/fan and that means some physical/money operation which is a boring way to start.

Setting your voltage to "Auto" is the first thing you should correct. Set it to manual and then set your voltage to whatever the VID is of chip. By manually setting the voltages, you have the control of how much as opposed to the bios doing it for you at a higher rate. Stability as nevbie has mentioned is what you are trying to accomplish. Heat will raise as you bump up the voltages as your OC gets higher.

Ram should be set to 1:1 ratio to remove it from the OC equation. If you are using a stock HS, your temps wont be as low as compared to an aftermarket HS so, If you don't have 1, you might want to check into purchasing one as this will help considerably by lowering your temps.

Good airflow in your case can help also. So, keep this in mind too.

Where is the cpu VID at in bios?

If you download coretemp and install it, it will give you your vid.

New HSF?

 

[bizzyd1441]

I bought an aftermarket hsf for the cpu right after I got it. Intel's stock hsf would fall off while it was running and the cpu would immediately shut down from overheating. This happened several times.

Hmmm sounds like it was not installed correctly...."drum roll"

70 Idle is dangerous too BTW...

If you intend to stick with air-cooling then by far the biggest thing you can do to reduce your temps is lap the CPU's IHS and the base of your HSF (provided its not a direct-touch heatpipe variety).

In some cases lapping your IHS and HSF has the double benefit to temperatures where because you lowered the temps with lapping you are now stable at your given OC with even lower Vcore...so reducing your Vcore at that point even furthers reduces your temps.

Something is really wrong here. Did you apply your thermal paste correctly? An E6300 will overclock to 2.0ghz on the stock cooler without any voltage adjustments whatsoever!

Also any good quality aftermarket cooler will max out an E6300 before temperatures become a concern. You either have awful airflow in your case, are living in Africa with no AC on, or your heatsink is not installed properly.

Anyone who has bought an intel chip knows they're heatsink fans are HORRIBLE. It uses push-pins to secure itself, and I thought I was going to crack the motherboard trying to get it in right. Even though it clicked in, when the computer was running it would party fall off and wouldn't be directly contacting the cpu. I have always suspected the cpu is damaged because of intel's crappy hsf.

I applied Arctic Silver and put a Zalman HSF on the cpu. I did it very carefully and there shouldn't be any problems there. My airflow probably isn't the best, but it definitely shouldn't be causing this much overheating.

Did you update your bios to the most recent version? Try different programs that monitor temperatures (Speedfan, Asus PC Probe, CoreTemp, actual BIOS)? Unless you have a faulty chip, there is no way you should be getting these types of temperatures. I say you reseat the heatsink again. Maybe you applied too much paste?

 

[nyker96]

well since no one mentioned this but I recond putting a large chunk of dry ice outtage lower the temp quite a bit :]

 

[bizzyd1441]

Well the dry ice approach is original.

I've checked the temp with CoreTemp and HWMonitor. I might just reapply the thermal paste and hope it changes something.
