Question 1

I just ordered this from Newegg and it's coming Monday.  I am using it for my HD 7850....radeons have the chip die as a diamond... This sink is sold as being compatible for Radeon and Nvidia cards, but it looks like out of the box the thermal paste or whatever is on the heatsink from the factory is square, not a diamond.... Do they provide additional paste? I don't think the square will cover the diamond die completely

Accepted Answer

Not sure as to exactly what your saying. But this will work the Radeons. I have one installed on my r9 290x and it works fine. Usually runs around 40 Celsius. 
It should work great on your card. If you do need more thermal paste. ARTIC Thermal compound is a good brand to buy. Though I don't think you will need to buy extra because the thermal that comes pre-prepped on the cooling system from the factory is usually enough. Hope this help answer your question.

Thanks,

Question 2

Hi, I've never modded a gpu before. but I'd like to. I have two 2 r9 290x gpus from powercolor. They have the reference cooler on them. I was wondering how good this cooler fits on a 290x and if the cooler itself takes 300 watts? That sounds like a bit much to power a cooler. Thanks in advance.

Accepted Answer

The cooler doesn't take 300w, it is designed to cool video cards with a tdp of up to 300w :)

I have this one on a 290 and it fits very good, temps are at least 20 degrees lower. I used a gelid kit for the vrms.

Question 3

So this is for my r9 290 and im already pushing my Power Supply i maybe have around 50-100 extra wattage to play with, i see the "300 watt" lable and im thinking wow does this thing take that much!? cant be... can someone explain more on this? Will i be ok with this? or do i need to upgrade my PSU and how much extra watt will this thing make my already 300watt gpu take?>

Accepted Answer

The cooler itself does not take 300W, it cools a GPU up to 300W. But honestly it can probably cool more than that. I have this with a 290x on a 620W PSU

Question 4

Compatible with EVGA GTX 780?

Accepted Answer

I have it presently installed on an EVGA GTX 780Ti, but this cooler is probably overkill. I was unable to make a stable overclock that improved on a more modest heat sink. However, if you want to lower your fan noise, this is your product. However, on my motherboard I wound up removing my USB 3.0 front case connector to make this titanic heat sink fit.

Question 5

Can this operate a standalone fan for my case.  My video card already has dual fans but my CPU runs hot.  Can this work without attaching to video card?

Accepted Answer

I would not recommend doing that. If your cpu is running hot I would recommend a liquid cooling setup such as the corsair liquid cooling H50 or the H80i which are sold here on newegg. Not only are these comparable in price but they are actually designed for that purpose and evacuate the heat from the CPU directly to the outside of the case efficiently. I have had a liquid cooling H60 on my CPU for 4 years and have not had any issues (hexa core I7 sandybridge)

Question 6

Is this VR-Ready?

Accepted Answer

This is A COOLER for your GPU. 
Nothing about is VR, but if you have VR GPU for this beast - it will cool it like a champ.

Question 7

This product can be compatible with XFX Double D FX-797A-TDBC Radeon HD 7970 Black Edition?

Accepted Answer

I have and XFX HD 6950 Double D and it fits mine, the cards are about the same dimensions and it is compatible on the list so yes it should fit. Word of advice though, this cooler is huge, it takes up on space above the card and three below the card, make sure your case and motherboard have enough room for it if you do decide to go for it.

Question 8

Will this fit the evga 680 4gb classified version of the gpu?

Accepted Answer

The Classified series of video cards from EVGA generally use a custom pcb.  So while this cooler is compatible with a "reference" 680 video card, there's no way to know for sure if it will work on EVGA's custom pcb.  That being said, it looks like someone on the EVGA forums did successfully install the Xtreme III cooler on their 580 Classified.  Since the Xtreme IV uses the same mounting holes as the Xtreme III, my guess is that this cooler would indeed work with a 680 Classified.  Keep in mind that the Classified series of video cards tend to have pretty good coolers on them already, so this Arctic cooler may not help a huge amount.

Question 9

I have very little room for the backside of my card.  Two of the screw heads for the stock heat sink are already in contact with the heatsink of my cpu.  Without the heat sink, how far to the posts stick out the back?  Is there a way to reverse them or use an alternative nut and bolt that would be less obtrusive, maybe even possibly use the stock screws?

Accepted Answer

If you can barely fit the stock heatsink without touching the cpu heatsink then this one will definitely not fit. The posts stick out at least an inch and they need the backplate in order to attach. If you went with this cooler I would recommend an earlier model without the backplate (which i'm not too big a fan of in the first place)

Question 10

I wonder how it's suppoed to be installed to cool down memory chips on RX5700XT?

Accepted Answer

As a person installing one on my GTX 1080ti I can tell you that there may be fan-wash that crosses the chips, but if you have special concern for RAM temps then you will want to buy some thermal-taped heatsinks to stick to them.  This cools almost /exclusively/ the GPU itself, though again, 'fan wash' may do a bit for most not-too-hot RAM chips.  YMMV, and all that.  RAM heatsinks and heatsink tape might not be a bad co-investment with this cooler, though.  Mine is installed, but I need to plug it in and use it to see how it behaves, so I can't say how much of an issue RAM temps may be for my 1080ti.
