Vortexx - Ideal Replacement For Stock HD4850?

[Nelsaidi]

Fine ... - Dont really care since I've had it for 18 months (at those temperatures its a miracle its not dead yet ) - But is such a mod compatible with othere coolers - or are there any other coolers equally good and silent, but more expensive - which will do the job of VRM AND GPU cooling at the same time?

Meh - It is a cutting time! - So, I still ned ~£3 of stff to get from Scan - Perhaps some lights to enhance the blue glow xD? - Getting AS5 (or maybe MX3 - need this next week - cba to go a few miles and pick it up when i aint home)

I attached one to my 4850 a few weeks ago. I bought the zalman heatsinks for it. Works a treat however the fan uses the standard 3pin plug that fits on to the motherboard and at stock voltage it is actually louder than reference cooler at idle However because the fan speed does not change (at load) it was obviously quieter compared to the fan on reference cooler that begins to spin up. When I game I use a headset on so any noise is generally unnoticeable so I don't really care about noise at load.

The only reason I bought it was because I damaged the fan on the reference cooler and I would have happily keep with the reference cooler.

For temperature off the top of my head, under load it is around <70c and at idle <55c.

In my honest opinion, was it worth the <£20 to get the fan+heatsinks? Not really. The temperature drop is a plus, but the noise (at idle) for me is a big minus. It takes up over 2 slots aswell. Annoying.

Oh, btw if you want to sell your reference cooler fan, I take it.

I idle at 90c - And during gaming it goes on full blast - thats annoyingly loud - THATS why I want a new cooler - I'd go passive but case cooling sucks - 2 Antec Tricool fans at low - both outtake. And that seems the vortexx reasonably cheap option.

I dont mind at how big it is - PLenty of sdspace, what I need is good and quiet cooling - even at load. (mind you putting two intake fans and all at max makes no impact what so ever)

lol mine was only 80c at idle, and 90c at load. The fan never spun up to 100% though, only around 70%. The Vortexx will be louder than your Tricools, btw, I think you should make one of the intakes, you have 3 fans shifting air out (inc psu fan) so where is the air coming in?

I agree, the akasa is the cheapest 3rd party gpu cooler, everything else is over >£30 and the if you don't use a headset or speakers turned up, the reference fan can get annoying.

My vortexx neo keeps my temps at 30 degrees idle, 45 max load. And its silent on my pc, cant hear it at all.

Pressure xD - Less air in than out, so it moves in - I dont need any need for it - I had two Zalmans at 50%, but they hardly did anything - CPU is at 3.6ghz and 50-55c load - No need for intakes - They didnt effect graphics either.

:S - Abit of a pickle we are in here :/ - I really liked it at £12, then remembered I need the cleaner - £16, acceptable - Now some AS5 - £21 - so, not that cheap! 20% of the cards price for a low end cooler. - £26 if i decide not to saw/axe/chisel/laser-cut through my current cooler. EDIT: Ram heatsinks have thermal paste applied \o/ - so £5 less. Also, nice Asus mobo lets me set fans at 60% or 100% - should be variable - meh.

Infinite, what did you do with your stock ?

[Infinite]

you mean half of the card's current value (£45-50). You can use vodka to save on the tim cleaner.

Edit: My stock cooler is in a box somewhere. The heatsink part in still intact because I didnt fancy spending +£20 on a good hack saw. The fan is probably on some landfill. XD

You also get thermal compound, ok its not AS5, but its "free".

For the money, coupled with the miniscule effort required to "modify" the VRM heatsink you wont get better. Spookily enoughI got similar results to Blaine when i had it on a 4850.

If my volt mod worked on my card, i would be running it at 800 core.

[Nelsaidi]

You know what - Forget this thread, I am implementing my ultimate 20p mod which will solve all my loud fan problems! - Brb 20 minutes!

Wasnt a successs - Plan didnt work as expected (build a fan filter for the hd4850 after giving it a full dust cleanup)

The other option is still the good old Accelero S1 rev2 and cable tie a 120mm fan to it.

Yup I used the Accelero S1 before and cable tied a 120mm fan on an 8800GT and it was silent on full speed pretty much. It was at 53 degrees load in Furmark, can't remember what idle was but I was surprised it's cooler than my 4770.

[morda8]

i had the exact same problem as u but since i bought my hd 4850 from pcworld i went there and got a replacement

the stock hd4850 is absolutly crap just like u say because after 6months or more it gets clogged up with dust which baisicaly cancels out the cooling...i hope the same doesnt happen to my hd5770

[Pob255]

For such a high temp card (both gpu and prm) it alwasy struck me as folly that ati made a single slot cooler for it, which was just a basic heatsink and a fan.
The 3870, 3850 and 4850 have all suffored from bad stock coolers

[Blaineoliver]

People loved the fact it was single slot, people also hated it the enthusiasts who wanted to overclock, if they did two SKU's people would have loved it.
