Duron 700 no OC yet already at 47C =(

[Chicharon1]

im currently using a Global FOP32-1 w/ thermal grease on my duron 700. im just running at 750 now n my temp is 47c already. i haven't adjusted the voltage. my mobo temp is 34c.

i have one fan at lower front blowing air into the case. another one below the power supply blowing air out of d case. what other things can u recommend that i can do to lower my temp to 30+C the hottest temp here in the Philippines is 38C during the summer and itz summer time!

cpu readings are sometimes wrong...also...your fan may be defective try another and check temps...

Okay, lets do an assumption and some math. Lets assume you are dunning your CPU at 1.6V. That means it is generating 31W of heat. With a system temperature of 34C and core temperature of 43C, your FOP-32 is delivering a 13C change in temperature. Given a 13C change at 31W, it is performing at about .41C/W. That sounds typical for the FOP-32, so your HSF is doing as expected. I used to use an FOP-32 and with room and system temperatures in the 20-25C range it was very adequate. You need to lower your room/system temperature for better core temps which will go up when you OC. If that is not a cost effective endeavor, then you need to get an HSF with a lot more capacity, like something in the .2x C/W range. Even going with a .2C/W HSF, your core temperature will only improve to 40C under your current conditions.

ah ic... .i just stuck a fan beside the FOP32, now my temp is down 4C to 45C.
i'll try another trick later... am i right that i should have a fan below my case blowing air out?

thanks for the math compu.. so now i know that it isn't with a faulty fan.. i'll try to push the temp down. What other fan positions do anyone of you recommend?

From what I've read about fans you need to maintain consistency. YOu need to actually make your case a duct that will suck air in and blow it out at the same time. I have 1 90 mm intake fan on the front below my drives. I increased airflow by cutting the grid over it and drilling small holes into the front of my case. With my case it is hardly noticeable. Next, I installed an 80mm (biggest I could fit) in the back right below the power supply to draw air out. This creates a current that will draw cool air in the front, bring it over the motherboard and cpu and then hopefully draw it out.

Remove the sides,also make sure that heat sink is sitting nicely on the processor,If you can put some artic silver between them it really makes a difference in cooling.

My Mid-tower case (Enlight 7237) came with 2 assist fan cutouts. There is one at the bottom of the front and one at the top of the rear, just below the PSU. I set my system up as a push-pull, with room air coming in the lower front and exiting at the top rear with a pair of 80mm Sunons. The two keep my system temp about 2 degrees above my room temp.
Here's where it gets weird. My HSF, which is about 4 inches from the rear top exhaust fan really screws up the airflow. It has a Delta 68cfm (you read right) on it blowing into the heatsink. It fights with the, wimpy by comparison, Sunon for the air at the top of the case and wins. It blasts the air back down into the heatsink where it then washes back over the motherboard. That is my only beef with the Swiftech MC-462A heatsink. Had it been designed as a suck fan heatsink, the exhaust from it would have rushed those 4 inches into the the top rear case exhaust fan instead of fighting it.

when i bought my case 2 years ago. Itz one of those original ATX casings that weight a TON!, it had a fan blowing into d case. at first i thought it was pumping dirt into the PC. Now i know that itz pumping cool air into d case.

i put a fan below the PS just like what i've been reading here. the i put 2 fans stacked on the right of d global win to force air into the processor and direct to the fan below the PS. am i doing it right?

i did put thermal grease between the processor n FOP32... we dont have artic silver here... it took me 2 weeks just to look for thermal grease here.. ppl in hardware/electrical stores doesn't even know what is thermal grease! i just bought some from a store selling cheap heatsinks!

thanks for all d help ^__^
