What temps should i get?
I have overclock my 3770k to 4.5GHz and wanted to know what temperatures i should be getting when stress testing it.
That depends on:
1-Room ambient temperature
2-CPU cooling system (heatsink and fan or water cooling)
If you are asking about what temperatures are safe, then I would say 75/76/77/78 degrees Celsius at full load is the maximum safe temperature. Anything above 80 can shorten the chip's lifespan.
To many variables to really answer.
1) your 3770 should start to throttle around 95->100C.
2) What HSF. If it is the Intel "stock/boxed" HSF bear in mind This HSF is at the BOTTOM of the heap as far as performance goes. Personnally I leave it in the Box, have to save in rare case you need to RMA the CPU. I alway buy a 3rd party HSF. The Intel is barely OK for stock Speed, even here it will run 5->10 C hotter than a 3rd party HSF when the CPU is loaded.
3) Another factor is your case / case fans and your ambient temperature.
4) Good application of HS Compound vs bad application
5) Temps GOOD HSF and based on 20->22C ambient
.. Idle speed. Individual cores 5 -> 10 C above ambient - Generally in the 30's Normally not a problem, but if hitting mid 40's at Idle generaly your loaded temps will also be high.
.. For Loaded, probably about 20C above ambient would be a good temp. Loaded Temps are much more important and personnally I like to keep in the 60's. Low 70's is OK, 80's to hot for my blood.
Effect of ambient (room Temps)
Ambient temp - approx 20->22 C. For every 1 Degree F, the cores will increase about 1 degree C
Ex: if at Idle and room temp is sa 22 C (72F) a good tem would be =<31C, But if room temp is 80 F (+ 8F) then expect cores to be about idle temp to jump to low 40's. GREATER effect when Loaded (do no know the corralation for Loaded, maybe +2C for ever 1 F increase)
There is several degrees difference in ambient temp based on location of the Computer - ie setting on the floor verse sitting on the desk. My computer sets on floor (have rug so used a piece of plexiglass to set it on plus it is located about 3 feet from a A?C vent so the "abient" temp of air sucked in is almose 5 degrees cooler than the thermostat when a/c is on, when a/c is off still about 2 degrees cooler.
The ambient temp is 26C and i have a h100i with arctic cooling mx4 thermal paste and a voltage of 1.255v.
I get up to 80C and stop because i don't want it to go higher but before with the original thermal pad put on by corsair i used to get low to mid 60's. Does this suggest i put too much thermal paste on or have i done something else wrong?
Based On: http://www.guru3d.com/articles_pages/corsair_h100i_review,11.html
Their test probably at 20->22 C.
OC @ 4.5 GHz w/1.20 Volts - There min temp was 65 C
Based on a ambient increase of 4->6 C Plus a increase in Vcore of =.05V, your 80 C may be close to correct.
However, I do Not use H20 coolers, so may be a minor problem with setup. On HSF Paste - Generally the less used the better - AS long as Complete coverage.
or a "flat" surface HS, I use about a pea size on the bottom of the HS nd spead with finger (use a latex glove), Then On the top of the CPU I put a very small amount and use my fingerto just barely cover.
