Better cooling before higher voltage

[batboy]

Hey folks, I know we preach that with the Intel chips, higher voltage seems to help with overclocking stability...but please, we need to do the cooling mods FIRST.

Both overclocking and using higher voltage increases heat to the CPU and to the motherboard. Heat is the enemy. Deal with the cooling issues before overclocking and raising voltages.

Too many folks are frying their CPUs because they have a retail fan and heatsink on it and bumping up the voltages to obscene levels.

Cooling, cooling, and cooling are the three main things to remember when overclocking.

I'll second that, with the default intel cooler stay under 1.9v, with a decent cooler like the FOP 32 stay under 2v (you should get away with 2v if you have good case cooling as well) it isn't worth pushing for an extra 20-30mhz by setting to like 2.2v as you have that extra <5% speed for a few months unless your one of these really lucky people who run at these high voltages for ages

Couple higher voltages, with the onset of summer in the northern hemisphere..and I don't think that your message can be stressed enough, batboy.

The confluence of two influences that can make overclocking a less than rewarding experience.

Since cooling is the topic on this thread, let me ask a question that is probably dumb.

On the Abit bx6 R2, the cpu temp is measured with a diode that is taped to the heatsink. So I have a cool heatsink it says! But how do I know if the cpu is cool?

And do other boards do it differently?

you can touch the sides of the heatsink and if it's cool you wont burn your finger M\board's do have different means of temp reading I think most use thermistor sensors one on MB for system temp and one in the socket under the proccesor some MB do not have any.

if your diode or thermistor is taped to your HSF then it will be measuring your HS tempature more so then the actual proccesor temp some people will drill a hole in there HS so that the thermistor will be rite on top of the proccesor in the middle of the HS but there using a different sensor then yours so I would not go drilling into your HSF

Hmmm.

Since I use a slotket (MSI 6509), then it would have to be the slotket that had a board mounted sensor. Do some slotkets have this feature?

In the case of a Slot 1 processor, there would be no sensor other than one like mine that mounts on the heat sink.

Using up heat sink contact area for a heat sensor would detract a little from heat exchange I guess, and the reliability of the reported temperature would still depend upon how well the sensor contacted the processor which you could not know for certain.

I guess you never know for sure when it comes to CPU temps, so you just have to practice as much overkill as possible when it comes to cooling.

BUMP. Good heads-up.
