    Hi there,

    my buddy asked me about D9F for rendering.

    Does anyone have any experience with rendering? Is there some overheating ?
    I have no experience with rendering but he says it might be running 24hours 7 days in row.... is D9F okay with that?

    What is the best cooler available for it - the coolest one the silent one.


    Thank you in advance.

    i use my D900F for CFD analysis, which might cause a similar load ... all CPU cores on 100% for hours to several days, 6GB RAM almost entirely occupied, heavy I/O operations on 10GB+ files ... and i had no problems so far

    Well it seems okay. In the review gophn says that in 8 threaded apps CPU reach 90C. What CPU do you have fenyk?

    What cooler do you suggest to buy ? The one with best cooling , dont care about noise.

    i have the i7-920 which seems to stay rather cool judging by the outlet air. i will have a look at the exact temps during the next solver run.
    i never run more then 4 threads on a scientifical app, scince dividing a workload in multiple parts always involves some overhead (e.g. 2...5% for average cfd problem) ... this will probably eat up most of the theoretical speedup those extra 4 hyperthreading cores would give

    ah and i've never used a supplemental cooler so no advice on that

    Okay from what I know D900F reaches up to 90C while 8 threaded apps are in use. When using best cooler available NC-2000 there is no guarantee this will help keep it under 90C.

    What do you guys think about undervolting? Will be Core i7 950CPU 100% stable while undervolting ? Will this help to keep temperature under 90C?

    Thank you for your answers in advance!!!

    If you wait 3 weeks for the CeBit in March, the new machine probably E9F will be there with a better CPU/GPU and cooling system ;) Worth to camp a bit.
