Can you overclock with a standard cooler/heatsink?

No, it's fine-I've done it with my E4500. As long as you don't get to the stage where you need to up the voltage it should be OK. I've hit 2.9Ghz stable with it.
 
the stock amd one isnt very good at all

i used it to have a go on my old X2 4800+
it went from 2.5 stock to 2.8 then crashed lots
temps of about 50-70

put an old thermaltake orb thing on it and it went straight to 3.1 no problems
temps of about 15-27

its now in my htpc under a scythe mini ninja at great temps with the 3.1 overclock applied
silent too

so in response - for the price of a third party cooler and a bit of arctic silver

£20 total

you would get much better results and not risk damaging your hardware

problem is the intel stock cooler is a lot better than the stock amd one
 
shorten life ? come-on from probably 20 years to 18 !

anything sub about 77C will not shorten the CPUs life

as a guide I have my Intel 2180 on stock cooler - at 3.0 gig (50% overclock) - max temp under small prime about 73C

so yes you can - and substantially too - 50% is more than people are getting out of E8500s with fancy cooling !

73C MAX > Intels info on their C2D.

Thats not to say you are to run it at 73C 24/7 as there is no need to reach that temp.

You pay a lot of cash for a good CPU, spend £15-30 on a good Heatsink to go with it.

Stock Heatsicks are crap and loudish, for £15 a Artic Cooling Freezer is far better but it will limit OC'ing as its 90mm and loudish at full speed, best go 120mm Cooling.
 
73C MAX Case temp - I'm sure

measured in coretemp etc = die temp - so even at 73C die temp I'm sure you're a good 10C off throttling

I used to worry about temps - but how many of us keep our CPUs more than say 2 years ?

just checked - and yes intels max in spec is 73C Tcase - not what we are measuring - so at 73C you're way off

do you not think intel would set their throttling to a temp below that which does damage - and certainly the CPUs current ones don't throttle till over 80C die temp

I do agree re noise though - stock coolers are not that quiet - and tend to have cheap fans with noisey bearings etc

Stock sinks are decent enough for Mhz clocks with stock or not too far from stock voltage as temps don't usually increase that much. Cpus with as much as 1Ghz (for example) between them use the same stock sinks in many cases :)
 
AMD

You will be fine - just don't up the voltages.

In my experience you can OC the AM2 Duel's by about 200mhz before you need to start messing with voltages.

For example I used to run my 4800x2 (stock of 2.5) at 2.7 taking upto the same speed as a 5400x2 (Im now at 2.85)

All you need to do -
1. Increase the speed up by 5
2. Test stability if ok goto 1 otherwise go back a couple of mhz and retest

It often depends on your memory if you are struggling try setting your memory to 400mhz first and then tighten back up once you have found your overclock.
 
@ Buckster, What are you talking about ?.

Who the hell has a Case Temp of 73C, the Amb for them Intel readings is 22C.

Visit the Intel site and learn its 73C, that's not to say it Throttles at 73C, thats the MAX REC Temp (we all know about Tcase etc and the readings are all messed up for 45nm CPU for now).

Anyone that cannot cool a CPU to below 73C needs overhaul there cooling and if you see 73C Socket/Diode in any APP that's hot.

Encouraging peeps to cook their CPU as you only keep yours 2 years is not good advise, if you want to OC invest in a proper Cooler.

err ... I'm a Chartered Electronic Engineer ...

Case temp is not your PC Case temp !

the case of the CPU ie the bit you stick your paste onto ... which won't be the same temp as the die temp

Everyone and their dog is a expert so dont pull that old one on me I'm too long in the tooth for that.

You said " 73C MAX Case temp - I'm sure", That is your Case Temp, you think its the Temp of the Chicken in the oven instead ?.

Anyone running their CPU at 73C in Coretemp etc is running it hotter than it needs be.

Anyone OC'ing too far on Stock Cooling needs their head examined, esp as £15 can sort it out.
