    CPU Temp - Potential Issue after upgrade

    All,

    Those that saw my recent build thread will know that I just upgraded my PC from an i3 2100 to a Xeon E1230.

    All went smoothly with the upgrade but I thought I better check temps and what not before signing the work off.

    Idle temps seem fine, but when I run some torture tests, the CPU runs at 92-99°C at 100% load. The TJ. Max for the chip (as given in RealTemp) is 105°C so I am not over this, however I am still a bit worried.

    Should I remove the HSF and re-paste and try again?

    Yep, start with the basics. Check mounting / paste.

    It'll start to throttle once it hits the TJMax, so it shouldn't cause any issues, but obviously you don't want it running like that.

    Re: CPU Temp - Potential Issue after upgrade

    Certainly seems high, but the HSF you're using is the CL-P0534 (slim x3) isn't it? What temperature where you getting on your old i3? The first test I found with that CPU cooler was here http://www.hardwaresecrets.com/artic...-Review/1221/6 done with a 95W CPU and it was hotter than the stock cooler. Your new CPU is 80W, which is from memory 15W higher than the SB i3s.

    It would certainly be a good idea to check the cooler, but if you're in a small case with limited airflow, it just may not really be able to cope very well . Hopefully it can though and it's just a mounting error

    Yeah, I am running the CL-P0534. Temps with the i3 were 35°C idle going up to about 75ish under load.

    OK. Well I have just replaced the HSF and the temps remain exactly the same, so I am leaning towards this being a combination of the HSF being not up the job, and the complete lack of airflow in the case.

    Now the questions is, do I live with it (idle temps are fine - 37°C) since it will very rarely be under 100% load for sustained periods, or invest in a better HSF?

    I am looking at a Noctua NH-L9i as an option.

    What do you guys think?

    Re: CPU Temp - Potential Issue after upgrade

    The L9i isn't really designed for loads this high - it doesn't really want to have over 65W put into it, it should work a little better than the thermaltake but I'm far from convinced it would be worth a £35 investment. Do you think something like the Geminii M4 might fit you MoBo and case?
    However if you rarely stress your machine completely then it'll probably be fine - if you're a gamer try some actual real world games and see what the max temp. is.

    Re: CPU Temp - Potential Issue after upgrade

    Personally I'd want to get those temps down a bit as you're probably nearing/hitting throttle limits - presumably you upgraded the CPU for a reason so you want to be able to use the extra performance available.

    What sort of case do you have?

    Edit in response to above: Depending on the case layout, playing games will likely cause heat to rise from from the GPU to the CPU intake, further exacerbating the problem.

    The Geminii would probably fit, but it would be a squeeze, which would just reduce airflow even more as the HSF is competing with the PSU fan for cool air :/

    To be honest, I am not really going to be able to leave it. The PC is a lot louder now even under idle as the fan is running at top speed just to keep temps reasonable.

    I suppose I could try another 80mm fan on this HS and see if that improves matters?

    Yeah, air flow is a real pain with the case. Worked fine with the i3, but its causing me issues now!

    Re: CPU Temp - Potential Issue after upgrade

    looking at your previous thread I'm assuming this is a Lian Li Q11. From looking online AIO watercoolers are a no go unless you mod the case so the PSU sticks out the back a bit leaving you with a very limited choice of low profile heatsinks. My suggestions would be: did your new CPU come with a copper cored heatsink? The stock intel heatsink from a 95W unit may well be able to cope on that new 80W processor. Otherwise it would appear that even though it isn't designed for it the L9i can cope with a stock 2600k http://www.tweaktown.com/reviews/513...ew/index7.html which is 95W, so that should be an option of you can sink the cash into it.

    Yeah, the stock fan has a copper core. I will give that a go tomorrow and see if it helps matters. If not, looks like I will have to invest in that Noctua HSF :/

    Re: CPU Temp - Potential Issue after upgrade

    Just a thought, what about flipping the CPU fan over so it matches the airflow direction of the PSU?

    Nice idea, but it turns out the fins on the fan catch the heat sink :/

    However, I have swapped the HSF the the stock Intel cooler, and temps are way, way better! Idle temps are the same (35°C) but the temp under 100% load is a much more reasonable 74°C across all cores.

    It's also a fair buit quieter both idle and under load, so good job Intel!



    So, I am going to do a few more torture tests but, I think, it's issue sorted!

    Cheers guys! Best PC community on the 'net for sure!

    Re: CPU Temp - Potential Issue after upgrade

    Glad to hear it, those copper cored heatsinks really aren't too bad for reduced TDP CPUs, I'm thinking about one for my i3, they're so much more efficient than the solid alu ones (obviously) and have better mass and surface area than your old cooler. If the noise isn't offensive to you then I'd say you're sorted
