The spec of dust was on the lens
This is one amazing piece of art all by itself... and it creates art...
Shouldn't that do something to the space time continuum or something???
Nice work man

Thanks guys. Actually I did some camera sensor cleaning, so there shouldn't be more of specks on future photos
A small update from yesterday - new 240GB SSD Crucial MX100 replaced a good old but full 120GB Intel 520. But I still severely lack of demciflex filters. Hope to get them this month.

I was thinking yesterday..how do magnetic filters "stick" to aluminium? As from my childhood I remember magnets are not influencing that metal =)))

Good remark Glimpse. They don't stick. They have a magnetic frame with glue to which the filter is attracted. But the frame itself will be applied to the alloy case via the glue.

Guys,
I am aware that this is not relevant to any real life rendering speed, but playing with a preliminary scene I noticed I just broke 1000ms/s. And the temperature was between 40-44C.

Wow.. That is fantastic perfromance with fantastic temp!!!
I always wondered when ghaving watercooling the gpu have low temps, but the produced heat is transferred to the radiator...
The room is still getting heated by air coming out of the radiator, right?
And can you compare that to the heat coming out the PC with aircooling?
Cheers,

That's right - heat has to be dissipated somewhere regardless you are on water or air. I saw Linus getting a massive rad out of a room to a roof - that is a way to keep a room cool

I like this Linus guy... fun to watch... high tech? low tech?.. don't know what I was watching here
Anyway... you can not say with watercooling the outgoing heat is less or more then with aircooling?
yes, both solution will heat up your room for sure... energy drawn by PU will come out as heat whatever solution, right?
In the winter I can shut down my house radiator and leave the door open, but in summer my room is too hot to be in for normal human being when rendering 
Next summer I will hopefully het the PC's in bigger working space and set them on one side of space and install aircooling to get the heat out the shortest way. Anyway, this is outside this thread, sorry.. was just wondering about the heat with watercooling 
Cheers,

Same here.
Watercooling also dissipates heat into a room (physics tells me that the amount dissipated shall be the same as on air). When ambient is 25C, water is +1-2C higher, when rendering - water is +10-15C higher. So overall temps on all components are incomparably lower than on air but heat goes through large radiator surface. PSU dissipates lots of heat which affects overall ambient temp.
That is right - larger and well ventilated room in summer is necessary, or good air conditioning, which I unfortunately lack.
Watercooling may slightly less affect the ambient room temp or slower heat it up - some energy is stored in water until fans push hot air through rads into a room...
