mmm no, thats just not true, they can say whatever they want but those little circuits are gonna break down faster under 90 C and beyond.

According to him, you cant get VRM below 60c. When mine maxes out at 29c in furmark. I really dont think this guy knows what hes talking about.

i think you are really confusing it. Show us a screenshot of your GPU running 100% with recorded screenshot of said temperatures. HWmonitor or HWinfo will show temperatures.

What are your ambient temperatures your weather where you live?

Pictures or it didn't happen.

Ambients must be like 15c to have 30c vrms in furmark or your card is throttling all to hell.

With 290X VRM1 is always hotter then Core Temp. Also for most people water temp ~ 24-28C so there is no way VRM can be close to Water Temp. VRMs hit 50s if cooler properly. EK block for example comes with really bad VRM thermal pads. My card when mining would hit ~ 80C in VRM1. Bought some better thermal pads and temps dropped to 55C.

Easy to get 50-60c on them when office temp is 70F-80F. Mornings temps low as 55f-65f its real easy to get 25-40c. Im only running rx360 v3 and a rx240 v3.(both 56mm) WIth a 270 res d5 pump combo. Not the best but is gets the job done.

The blue uv hose is pretty sweet though.

Ill admit that, that aqua full cover card does look really cool. Im just an XSPC nut lol.

So, judging by the discussion, it seems that I'll be wanting a full coverage water block because I want to keep the vrm as cool as they can be. Am I correct in this conclusion?

If that's the case, then I still have to decide which brand to get. Here's a list of the blocks that I could find (all from frozencpu for the sake of consistency).

XSPC - $136.99
Koolance - $134.99
Heatkiller - $144.99
EK (Copper) - $109.99
Aquacomputer - $132.99

I'm tempted to just get the EK one because it's solid copper (so no flaking issues) and it's the cheapest, but I have no idea how well these brands compete in terms of quality and efficiency. I don't care how it looks, my only concerns are the cost, performance, and compatibility with my current hardware and loop.

Also, frozencpu has never let me down before, but if there are better options for distributers, please let me know.

Thank you all so much for helping me out on this. I love learning about all this stuff, and it's incredible that so many knowledgeable people are willing to help me out. That being said, which brand should I get, and where should I get it??

The AquaC or Heatkiller block,best quality blocks you can buy,however the Heatkiller doesnt cool the back of the card at all.
The AquaC block with the active plate (if you can get one) is hands down king of VRM temp reduction.

Ok, so here's the only place I could find where they were in stock, and the price is a little steep for me. How much of a difference will it make? I mean, for a college student budget, is it worth it? Plus, apparently getting it from Canada is a slightly higher price (duties and what not).
