[Q9550] Lowest temps under 100% load on all 4 cores?

mrk · 25 Jan 2010 at 01:17

Previously I've never really tested temps by maxing the cores in the real world (and as such the stability of the overclock) but tonight I left a video to encode using Handbrake and I am quite pleased with the temp not going above 56 degrees with all cores maxed and me watching a movie + surfing.

It's a 1.2750v VID Q9550 at 3.4 (8.5x400) and 8GB RAM at 1:1 // 5-5-5-12-52-2T - using an Ultra120 and Akasa fan at 848rpm.

Last time I used handbrake was when I had the Q6600 and that reached 65-70 degrees under load.

Lots of people have had this CPU before so I wondered what temps on what coolers people have gotten (or are getting) under these kinds of load conditions?

I noticed gaming in L4D2/TF2 etc don't tax it much at all and temps barely rise above 45 degrees and idle temps are 35-38.

That's pretty good, especially for a single fan at 850rpm. I was at 70 at 3.8ghz using a TRUE and 1600rpm scythe, or 55ish under water at the same speed. Then it died and I was sad

I think I know why it died

Yeah I am impressed with the CPU, I know the i7 chips will do it it probably half the time but I cannot see myself spending £300+ to upgrade only to lose some extra encoding time when gaming and OS usage will see only a minimal boost in performance!

Will perhaps even skip the i7 generation and wait until the next logical generation.

It's a pretty good temp that, especially with your low speed fan. It's a cracking CPU still and I don't intend to upgrade yet either.

Video encoding doesn't quite push the cores as hard as something like orthos does, although encoding is probably the toughest thing you'll do with your CPU for a long time period and in normal use.

I find that IBT will create higher temps than anything, and almost instantly, if you really want to see what temp it will run at.

This is the max i ever hit on mine with p95 fft, vcore of 1.216 at load, @3.8ghz 1.200 vid.

Was a really nice clocking, cool running cpu. Cooled by a TRUE black with 2 x 400-1200rpm pwm fans.

i'm currently looking at getting this chip stuck offshore atm ording when i get home i think :d

Ah, ran Orthos but it seems to only use 2 cores so I guess runing 2 instances is the way.

Anyway, Orthos temps rise to 61 degrees!

Try prime95 to load all four cores, or intel burn test, ibt will tend to generate higher temps than p95.

after 45 mins of prime and my max temps settled...

under an Alpenföhn Panorama 'Low Profile' CPU Cooler and the only other fan in my ITX case is the PSU

Stop whimping out, IBT for the real burn test!!

IBT was much better, 64bit and all 4 cores - and as such 68 degrees was the highest temp on a 10run session - completed nicely though and I found out my BIOS beeps when the temp reaches 66 degrees!

The great thing though is that the PU fan ramps up and down on the fly which is nice (BIOS controlled but I use Gigabyte ET6 to set the level it ramps up to around 1200rpm at (60 degrees) but the moment each run in IBT finished the temp dropped to 40 instantly so looks like my heatsink and paste install as well as airflow is nigh on perfect!
