With my block (Aquacomputer Aquagraphics) there is thermal pads only under VRM but not over memory chips. Should I use Fujipoly everywhere ? If yes , what thickness? Is it the same thickness for VRM and Memory?

My card has some coil whine, but only when I'm pushing it really hard; It can be hard/impossible to hear with an air cooler. I started fiddling around again to find suitable clocks for gaming and decided on +100mV offset and I'm stable at 1200/1500 with no apparent coil whine.

Is there a thermal pad roundup/comparison?

This is 17 W/m.K, so presumably some pads are better than others.

AMD Thermal Interface Material Comparison: Thermal Pads vs. Thermal Grease

Interesting. Thin Copper with TIM may be more effective than a pad. (unless electrical conductivity is an issue? Pads are dielectric.) I guess you'd anneal (soften by heating) the copper first .... if trying it.

No round up that I'm aware of, but waiting to hear from Gunderman456 about what kind of a difference the Fujipoly Extreme 11 W/mk make compared to EK stock. I observed 23% lower temps switching from XSPC stock to Fujipoly Ultra Extreme.

Another question, planning on doing a water cooled build, Should I get a EK R9 290x Acetal + copper or nickel? Planning on using distilled water with PT nuke. I heard about changing the thermal pad when applying the water block, What kind of thermal pads should I get and what thickness is needed? What is a good thermal paste I should use, Right now I have AC5 and swiftech tim mate...?

I have used EK Acetal Nickel blocks for HD4890, HD7870, and GTX 670 with no issues at all. The benefit of the nickel is obviously the bling factor and it cleans very easily. Bare copper will end up getting stained from TIM like a CPU heatsink.

See my link above; Fujipoly Ultra Extreme make BIG difference for me.

EK use 2 different thickness pads, 0.5mm for RAM and 1mm for VRMs. RAM doesn't get very hot so save your $ and use the supplied EK pads for that. I upgraded the thermal pads for RAM to the Fujipoly Extreme and observed no gains from the additional money I spent.

Just buy the $20 Fujipoly Ultra Extreme 15mmx100mm piece and upgrade just the VRM pads.



EK recommends EK TIM Ectotherm, Arctic Cooling MX-2 ™, MX-4 ™ or GELID GC-Extreme. I've had very good luck with Xigmatek PTI-G4512. Others like Noctua NT-H1.

Benchmark/Stress test are going to load everything more heavily than a game and cause higher temps. If you have no issues while gaming I wouldn't be very concerned, especially if your VRMs are maxing at 80C, you should be just fine.

It is writen - +12V1 - 24A and +12V2 - 24A; -12V - 0.8A. Are these ok?

And one more thing - my max temp for the core is 75 degrees and 77 for VRM1. This is with stock voltage of 1.156V. max under full load for more than an hour playing or benching heaven and valley. What do you think about?

I don't know for sure, I was trying to locate the pad thickness for the Aquacomputer block but it wasn't listed in the instructions. To be on the safe side I would say use 1mm for both the RAM and VRMs. If possible, try and measure the pads you were given to see how thick they are?

I wouldn't want to put TIM on the RAM chips, too messy to clean up IMHO. EK has a different procedure as well, recommending TIM used with the thermal pads on the VRMs. I just think that's too much hassle to clean up for likely minimal improvement in performance.

Temps are definitely acceptable for core and VRM1. If you are at 77 for VRM1 on stock clocks, you may not have much room to overclock or add more voltage. The general opinion/consensus in this thread seems to be that 80C is where people start becoming uncomfortable for that VRM1 temp. They are rated for ~120C I believe, but for stability and longevity best to keep them as cool as possible.

You don't need thermal pad on memory. Follow the instruction that come with the block. If I remember correctly, you only need put TIM on the memory. You should only put thermal pad on VRMs. I don't know the thickness of thermal pad the Aquacomputer kryographics use. The manual doesn't mention about the thickness?

[EDIT] Found it. The Kryographics stock thermal pad is 0.5mm thick.

The Kryographics blocks use the least thermal padding of all waterblocks: only for the VRM's. The VRAM is cooled by direct contact with the machined copper/nickel, so there only some TIM.

Officially, the padding is 0,5mm thick, but if the padding you're getting is more pliable than the stock ones, 1mm is also good.

I've got some Phobya 7w/mk and it does the job very nicely.

Kryographics waterblock is very good in cooling VRM1 compared to other blocks in the market. The stock thermal pad should be more than enough but you can always use better thermal pad if you want. @Raephen use Phobya 7w/mk & it worked well for him.

By the way my stock clocks are perfectly stable with -37mV offset. And we are talking for much lower temps - 69-70 for the core and 71-72 for VRM1. I thing that GB decided to reinsure... smile.gif And by the way on stock i can clock 1100/1500MHz, so it is not so big problem.

And what about:

And what about:

+12V2 is for CPU (ATX/EATX12V/EPS12V) & +12V1 is for everything else. This means, you have 288W for GPU & other components (except CPU) in your PC. Huh...did you ever overvolt your 290 before?

Yes - with +100mV i benched for an hour with 1150/1500MHz. A little bit high temperatures but the gpu was stable.
