HR-03-Plus Ram Sinks Q - Page 2

post #11 of 28
Thread Starter 
My epoxy arrive today. Although the instructions scare me. I don't have any silicone to put around the chips...

Do you think I could just put masking tape around the ram chips then while the epoxy is still curing take the masking tape off thus taking away the excess epoxy?

do not use cello tape, once it get hot enough it may not completely melt, but the sticky stuff will melt on the components, and it will be a pain to clean up, and plus the tape may let the ram get hotter rather than cooling it

Well I am running without ram chips on some of the ram at the moment with cool air being blown over it and it is ok.

I will put the epoxy on tomorrow.

Just put Epoxy on. Forgot it was my birthday yesterday so was busy.

They really are stuck on. One ramsink can hold the weight of the whole card plus the HR-03-Plus

Temperatures are good. With a 120mm fan blowing over at the stock overclocked I get 63deg max. With no fan 78deg max.

2 degrees below stock cooler with passive HR-03-Plus.

Idle temperature with stock cooler was 54deg.
Idle temperature with HR-03-Plus with 120mm blowing over it is 44deg.
Idle temperature with HR-03-Plus with no fan is 51deg.

The stock cooler temps are also with Arctic Silver 5 on the core.

FYI, you can also check memory temps using Everquest. I have my HR-03 plus mem sinks still in place with my MCW60 water block. With a fan blowing over them my memory is in the low 30s, GPU is idling at 35 and loading at 38.

I also used the artic adhesive as soon as I saw how poor the tape worked. They're stuck on there for good now.

I have an 8800GTX and the HR-03 Plus, and I didn't have a problem at all with the Ramsinks falling off... but I don't recommend permanently gluing them on there with adhesive. You may want to eventually take them off.

Do what I did and press down fairly hard on the Ramsink, and put a finger on the other side of the card to give back pressure. But press evenly and not too hard - don't want to crack the chips.

If that still doesn't work, I recommend buying some Ramsinks from Xoxide - like these ones - the sticky should be better, and they're also copper which will probably give you better temps.

Saying vRAM doesn't need "that cooling" is true, if you stay stock.

If not having them was just as good as having them, being "unnecessary", then you should have the same OCing headroom with and without.

I gained 30Mhz (60Mhz) on my 7600GT just by adding RAM sinks at stock voltages.

They are already on, and they are now staying on...forever

I did press them down firmly. The smaller 4 ramsinks that go on the top 4 chips were all perfectly fine, but 4 of the larger ones wouldn't stick. Luckily I didn't need 2 of them as there were 2 extra's but I put on epoxy on the 6 big ramsinks. I can't imagine myself changing the cooler on it anyway so it makes no difference to me. Just means I am screwed if the card buggers up now.
