**OcUK Extreme Haswell bundle - A review!**

I decided to delid my 4.6G bundle I7 4770K cpu as wanted to try for lower temps.
Before I started today quick prime was giving me 81C to 87C peaks across the cores.
My plan of course was for Liquid pro core to IHS and Gelid GC3 IHS to water block.

HOWEVER look what I found when I removed the lid which was very easy took about 3 taps with a very light hammer and vice.

Sure as hell looks like Liquid pro to me already applied to CPU!

Application looks thin around the middle though.

Anyway I cleaned it all up, including some laying across the resistors? Assuming it was dislodged onto them during the IHS removal.

At end of day carefully reapplying Liquid pro and using Gelid GC3 under the water block max temps in prime are now maxing at 57C to 61C across the cores.

Dropped 26C :D

I was under the impression these were sold as specially binned chips but not previously de-lidded.

Have to say the IHS bond to the cpu looked like it was original and had not been previously removed.
But it sure as hell is not the same TIM everyone else has had posted in pics.

Is that not grounds for a RMA ?

Intel don't guarantee that all their cores run at temp X away from each other.. they guarantee their CPU's work under the thermal target, which is 100 or throttling at 92-95. At stock clocks.

So nah :P especially since total temp is just fine.

OCUK can you comment on this?
 
That does indeed look look like liquid ultra/pro on the die of that chip. Ive used it enough times to know what it looks like. The stock intel paste is a dull grey colour like arctic silver. But that cpu in the pics does still show the black glue/sealant that secures the ihs to the rest of the chip. Another reason why haswell runs hot, not just the normal cheap paste, but too much of that black gunk.
 
That is definitely not stock intel paste on that chip. It's way too shiny compared to the stuff on a standard haswell or even an ivy cpu. Tbh, intel should get in touch with coollaboratory and get them to provide the paste for theese chips. It's pretty shoddy when the customer has to delid so that the chip runs better. Bit like buying a ferrari from a dealer but then you have to build the engine yourself.
 
They front a 2 year in house warranty on the entire bundle - including the oem chip. So you get an extra years warranty with it too over a stock oem chip.
 
Should have also mentioned that after cleaning all the old sealant off the IHS it would then sit on top of the core with a gap all the way around the IHS to the chip.

IE the IHS was able to rock over the core, so any kind of pressure holding the IHS down after application should prevent any bad contact between IHS and core.

I also applied a clear nail polish over the resistors? Having seen some of the original Liquid pro? on them after removal of IHS I was in panic mode and took forever cleaning it away and sealing them before risking fitting it.

The pic of the cleaned core shows what looks like scratches and pits in the core, so even more justification for a Liquid Pro type TIM to get right into them.
 
If OCuk do delid these, they should say it so the sales would go up :)

People are looking for professionally delidded chips all over.

I wondered how long it would take you guys to notice this.

& yes, we do use cool labs liquid.

Intresting, guess this would explain the slightly wonky ihs on my 4770 :D

Also, do you put anything over the resistors at the side of the die?

not at this point sorry

:( surely sales would go through the roof if you did, OCUK could gain in customer service by letting people that bought there kit form yourselves but were unlucky in the silicone lottery by offering to purchase a nice chip as long as they meet the criteria
All purchased from ocuk within last 12 months
OC mobo
4770k
Ram
cooler/waterblock

Win for OCUK and Win for the punter, albeit at a greater cost
 
supply is limited and there is a lot of work involved in selecting the chips. At the moment we don't have the manpower, or supply, to cope with a high run rate. We may as well keep them exclusive to our systems & bundles.

I may as well come clean, I had a fairly good idea this was the case as I was told from someone who shall remain un-named that this was done with IB chips.

Also the adhesive spilling out the sides of the chip was a bit of a give away :p

I didn't want to say anything as I wasn't sure if OcUK wanted everyone to know etc... thought it was best to keep it under my hat.
