Hi Guys, just got myself a Coolermaster test bench to test some of my used MB and CPU before I sell them, I just wonder as it will be on a open air test bench, will that be safe to test CPU without Heat sink and fan? or should be set a fan up to blow cool air pass the CPU just to be safe? any advices will be very Grateful....

Regards
Tony
 
Lol it's a bit stupid, but as I don't have a spare Heatsink, I was hoping I can do the testing without one, look like I have to go and buy a cheap one just to check it before I sell it, hehe...Thanks anyway matey...Regards
 
In most cases the CPUs will thermal cutout after about 15 seconds tops with a small to moderate risk of damage if you try to run them without a heatsink at all.
 
Cheer matey, just ordered a cheap Intel low profile heatsink for it, just can't do it the easy way i guess...Lol

Water and electrical components don't really mix too well :p

[yes, I know - whoooosh]


As others have said, don't try it. Modern CPUs put out an incredible amount of heat for the area they occupy. If you try to run them without any kind of heatsink then, at best, they will cut out very quickly even without any real load. At worst, you'll damage / destroy the chip.
 
Chip will shut down really quickly. No idea on AMDs these days but killing an Intel chip in such a fashion is more or less impossible.
 
Bad idea of course. However, I did flip one on without a heatsink to see if my bro's CPU was dead, or if it was something else. It wasn't that CPU and it went off in a second - literally.
 
I've turned on a motherboard with a cpu waterblock attached, but no tubes or water, to see if it reached the bios. That seemed to be OK. Don't do it with nothing bolted on top at all.
 
I lost my athlon XP 2500 barton when i managed to mount the cpu cooler wrong when in a hurry. Thermal cut out worked initially, but at that point, I hadn't realised why it shut off a split second after i'd switched it on, so I powered it back up. Virtually no contact from the heatsink and no more than 2 seconds on was enough to fry it. It didn't remain on or survive long enough to even show anything on screen.

The video online where they take the heatsink off the old Duron, whilst running, is quite amusing. What thermal cut-off? :D

Reading down, this is what I was going to post. Amazing video showing a cpu blazing itself to death.

*happy sigh*

AMD's used to be able to take some insane abuse :D

RE OP...think you getting the general idea that no heat sink is bad...m'k :)

Good chance that you'r CPU will go pop before you can test anything :(
 
Just stick any old heatsink on it. Snap the clips off of a Pentium 4 478 cooler and balance it on it, anything.
