New EK CPU block!!

[RLM]

Right some more tests.

Put the GTX back in a few days ago. Thanks to cutting a hole out of the back of the motherboard tray this is now a doddle to do.

I have a digital clock which has a thermometer built in and a fan (not blowing on kit) which also has a digital thermometer. The readings are 2c apart. I think the fan is probably the more accurate.

I kept the readings to 22c on the clock and 24c on the fan. This took a bit of work as the midday heat came. Had to tweak the aircon to keep ambient on level.

I ran some prime tests at 3.6 ghz and 3.825 ghz. As I say swapping the blocks was a doddle, so when I put the supreme back in I could leave the loop and
setup pretty much intact.

As per last test, sides off case and fans on the PA 120.3 at max. GPU at 1.47v. Both blocks were hard mounted with back plates and I used MX-2 thermal paste.

Note: I did 15 minute tests. I noticed that at Test 1 560000 the temps on the gtx jumped up a bit. More so than the supreme.

IDLE Apogee GTX 400x9 3.6 ghz.


IDLE EK Supreme 400x9 3.6 ghz.


LOAD Apogee GTX 400x9 3.6 ghz. Temps up to Test 1 560000 51 51 47 46


LOAD EK Supreme 400x9 3.6 ghz. Temps up to Test 1 560000 48 48 44 42



IDLE Apogee GTX 425x9 3.825 ghz.


IDLE EK Supreme 425x9 3.825 ghz.


LOAD Apogee GTX 425x9 3.825 ghz. Temps up to Test 1 560000 57 57 51 51


LOAD Ek Supreme 425x9 3.825 ghz. Temps up to Test 1 560000 55 55 50 49


One thing, I did mount the supreme the other way round this time. With the Barbs over to the right of the top. Supreme engraving on bottom and Ek on top.

My conclusion for what it's worth is that the GTX and Supreme are pretty damn close. The supreme is cooler though by about 2 maybe 3 degrees c depending on the overclock.

Just one thought though with the Supreme. Would like to see a bit of a redesign on the mounting plate. Due to the size and the layout of my motherboard I wasn't able to test out a vertical mount. On the Apogee GT bowed the V mount did seem to help a bit with temps. I also like the fact that on the GTX more of the components around the cpu socket are exposed for fan cooling.

Well that's my take, obviously look forward to seeing other peoples results. Either way a happy chappy
